Novel all-in-one data in mobile phone transmission security key signal is encrypted method and refers to an information (or title plaintext--plaintext) through encryption key pair (Encrypt ionkey) and encryption function conversion, become insignificant ciphertext (ciphertext), this ciphertext is then reduced into expressly through decryption function, deciphering key (Decryti on key) by recipient.Encryption technology is the foundation stone of network security technology.The method that in mobile phone mobile platform data transmission procedure, two key signals are encrypted requires only under the user specified or network, could password be removed and obtain original data, this just to need to data receiver and reciever with some special information for encryption and decryption, Here it is so-called key.The value of its key chooses from a large amount of random numbers.Private key and public-key cryptography two kinds is divided into by cryptographic algorithm.In mobile phone mobile platform data transmission procedure two key signals be encrypted method encryption time use same key, i.e. same algorithm.As the Kerberos algorithm of DES and MIT.Single key is most plain mode, and communicating pair must exchange key each other, when need to the other side's photos and sending messages time, be encrypted with the encryption key of oneself, and after recipient receives data, be decrypted with the key that the other side gives.This mode is becoming very complicated with during multi-party communication because of needing to preserve a lot of key, and the safety of key itself is exactly a problem.DES is a kind of cryptographic algorithm of packet, and data are divided into the data block that length is 64 by it, and wherein 8 are used as parity check, remaining 56 length as password.Original text is replaced by the first step, obtains the rambling data group of 64; Second step is divided into impartial two sections; 3rd step encryption function converts, and under given key parameter condition, carries out successive ignition and obtain encrypted cipher text.Public-key cryptography, also known as unsymmetrical key, uses different keys, namely different algorithms during encryption, have the encryption key that public, has many decruption key, as RSA Algorithm.In a computer network, encryption can be divided into " communication encryption " (data encryption namely in transmitting procedure) and " file encryption " (i.e. storage data encryption).Communication encryption has again node encrytion, link encryption and end--end encryption 3 kinds.1. node encrytion, from time coordinate, it carried out before information is passed into practical communication tie point (Physical communication link); From the coordinate (logical space) of OSI 7 layers of reference model, it carries out between ground floor, the second layer; From objective for implementation, be that the data transmitted between adjacent two nodes are encrypted, but it is only to message encryption, and not to packet encryption, so that the selection of transmission route.2. link encryption (Link Encryption), it carries out in data link layer, be to adjacent node between link on the data transmitted be encrypted, not only to data encryption also to packet encryption.3. hold--end encryption (End-to-End Encryption), it carries out at layer 6 or layer 7, be for transmit data between user and provide continuous print protection.Origination node implements encryption, transmits in intermediary node with ciphertext form, be just decrypted when finally arriving destination node, this leaks also very effective to preventing copy network software and software.In OSI Reference Model, except session layer can not implement encryption, other each layers can implement certain encryption measures.But normally encrypt on top, each application namely in application layer is modified by cipher coding, therefore can play secret effect to each application, thus protection investment on the application layer.If below certain one deck implements encryption, as on TCP layer, just can only play a protective role to this layer.Can it should be noted that and play the effect of encryption mechanism by efficiently and effectively, crucial problem be the management of key to comprise the existence of key, distribution, installation, keeping, use and calcellation overall process.(1) though the encryption mechanism of digital signature public-key cryptography provides good confidentiality, be difficult to differentiate sender, namely any people obtaining public-key cryptography can generate and send message.Data signature mechanism provides a kind of discrimination method, with the problem such as solve forgery, deny, pretend to be and distort.Digital signature generally adopts asymmetric cryptosystem technology (as RSA), by carrying out certain conversion to whole plaintext, obtains a value, as signature verification.Recipient uses the public-key cryptography of sender to be decrypted computing to signature, and if its result is expressly, then signature effectively, proves that the identity of the other side is real.Certainly, signature also can adopt various ways, such as, after being attached to by signature expressly.Digital signature is commonly used to bank, electronic trade etc.Digital signature is different from handwriting: digital signature changes with the change of text, and handwriting reflection someone personal characteristics is constant; Digital signature and text message are indivisible, and after handwriting is attached to text, are separated with text message.The user asked carries out authentication, confirms whether it is legal user; User legal in this way, then audit service that whether this user have the right to ask him or main frame conducts interviews.From cryptographic algorithm, its checking is based upon on the basis of symmetric cryptography.1. fail safe is high; the password of method to user that in mobile phone mobile platform data transmission procedure, two key signals are encrypted is encrypted the rear private key as user; thus the password avoiding user shows transmission on network, listener-in is made to be difficult on network, obtain corresponding password information; 2. transparent high, in use, only require input password when logging in, just the same with usual operation, the existence of Ker beros is transparent to user for validated user; 3. extensibility is good, and the method that in mobile phone mobile platform data transmission procedure, two key signals are encrypted provides certification for each service, guarantees the safety applied.The method server that in mobile phone mobile platform data transmission procedure, two key signals are encrypted and the secret that user shares are the passwords of user, and the authenticity of server not authentication of users when responding, supposes to only have validated user to have password.As assailant records application reply message, just easily form code book and attack.The method server that in mobile phone mobile platform data transmission procedure, two key signals are encrypted and the secret that user shares are the passwords of user, and the authenticity of server not authentication of users when responding, supposes to only have validated user to have password.As assailant records application reply message, with regard to easily being formed, 3. code book is attacked, AS and TGS is centralized management, easily forms bottleneck, performance and the performance and the safety that also depend critically upon safely AS and TGS of system.Access control should be had, to strengthen the safety of AS and TGS before AS and TGS.4., with number of users increase, key management is more complicated.Kerberos has the hashed value of the password of each user, and AS and TGS is responsible for the distribution of communication key between family.When N number of user thinks to communicate simultaneously; still need the method public-key cryptography employing RSA cryptographic algorithms that in N* (N-1)/2 key (3), PGP algorithm mobile phone mobile platform data transmission procedure, two key signals are encrypted, implement the management to key; Packet key have employed IDEA algorithm, implements the encryption to information.First feature of PGP application program is that its speed is fast, and efficiency is high; Another distinguishing feature is exactly that its portability is outstanding, and it can run on multiple operating platform.PGP mainly has the E-mail, digital signature etc. that encrypt file, transmission and reception are encrypted.(4), PEM algorithm all provides such as all messages: the security service functions such as checking, integrality, anti-repudiation; There is provided optional security service function, as confidentiality etc.PEM to the process of message through following process: the first step, make standardization processing: in order to make PEM and MTA (mail transport agent) compatible, by S MTP, standardization processing is carried out to message; Second step, MIC (Message Integrity Code) calculates; 3rd step, is converted into the message processed the form being suitable for SMTP system transfers.Identity validation technology identification (Identification) is that designated user shows the proof of identification process of oneself to system.Authentication (Authertication) is the process that system checks the proof of identification of user.People are often referred to as authentication (or identity verify) these two work, are two important steps distinguishing and confirm communicating pair true identity.The safe practice that Web adopts on the net realizes network security on the net at Web generally SHTTP/HTTP and SSL two kinds of modes.(1), SHTTP/HTTP SHTTP/HTTP can adopt various ways to encapsulate information.The content of encapsulation comprises encryption, signature and the certification based on MAC.And a message can be encapsulated encryption repeatedly.In addition, SHTTP also defines header packet information to carry out cipher key delivery, certification transmission and similar management function.SHTTP can support multiple cryptographic protocol, also for programmer provides ring of programming flexibly.SHTTP does not also rely on specific key proof system, and it supports RSA, band and out-of-band and Kerberos cipher key change at present.(2), SSL (Secure Socket Layer) SSL is a kind of industrial standard utilizing public key technique.SSL is widely used in Intranet and Internet net, and its product comprises the client-server of the support SSL provided by companies such as Netscape, Microsoft, IBM, Open Market, and the product such as such as Apa che-SSL.SSL provides three kinds of basic security services, and they all use public key technique.1. information private, by using public-key cryptography and symmetric key technique to reach information private.All business between SSL client computer and SSL server are used in the key set up in SSL handshake process and algorithm is encrypted.This prevents certain user by using the illegal wiretapping of IP packet sniffer instrument.Although packet sniffer still can capture the content of communication, cannot decode.2. information integrity, guarantees that SSL business all achieves the goal.If Internet becomes feasible e-business platform, should guarantee that the information content between server and client computer is from destruction.SSL utilizes secret to share and hash group of functions provides information completely sex service.3. certification mutually, is the process that client-server identifies mutually.Their identifier public-key cryptography is encoded, and exchanges respective identifier when SSL shakes hands.Prove that holder is its validated user (instead of the user that assumes another's name) to verify, SSL requires to prove that holder carries out digital mark when shaking hands to swap data.Proving that holder identifies to illustrate to all information datas comprising proof oneself is the lawful owner proved.This prevents other users to assume another's name to use proof.Proof itself does not provide certification, only has and proves just to work together with key.4. the Security Service of SSL is accomplished transparent as far as possible to terminal use.Generally, user only need click a button on desktop or connect and just can be connected with the main frame of SSL.Different from the HTTP connection application of standard, a default port supporting that the representative network main frame of SSL accepts SSL connection is 443 instead of 80.When client computer connects this port, first initialization handshake agreement, talks with the period to set up a SSL.Shake hands after terminating, will to communication encryption, and inspection message integrality, until this dialogue period terminates.Each SSL dialogue period only occurs once to shake hands.By contrast, the connection each time of HTTP all will perform once shakes hands, and causes communication efficiency to reduce.One time SSL shakes hands following for generation event: 1. X.509 client-server exchanges proves so that both sides confirm mutually.Whole proof chains can be exchanged in this process, also can select the proof only exchanging some bottoms.The checking proved comprises: the signature authority that inspection validity date and checking prove.2. client computer produces a group key randomly, and they calculate for information encryption and MAC.These keys first will be sent to server by the public key encryption of server again.Always have four keys and be respectively used to the communication to server of server to client machine and client computer.3. Information Encryption Algorithm (for encryption) and hash function (for guaranteeing information integrity) combine use.The SSL implementation of Netscape is: all algorithm inventories that client computer provides oneself to support, server selects it to think the most effective password.Server managers can use or forbid some specific password.

The Internet brings great convenience to people's life.But people at enjoyment network simultaneously easily, but often easily ignore the potential safety hazard that network is hidden.The development of information technology makes the double-edged sword effect of the Internet day by day manifest.Many lawless persons, illegal tissue or spy service also make full use of " dark place " of the hidden resource of network, the feeler of crime is stretched to other people, the individual privacy of other country, strategy are secret, wantonly steal or these information of illicit distributions, to reach specific object.

For enterprise; the financial expense situation of enterprise, project application and research and development document etc. are all very secret materials; some illegal competitors steal secret frequently by technological means; victim is made to suffer huge economic loss; thus; our network management personnel, while carrying out network protection and management, should note carrying out network security work.The many levels such as this paper maintains secrecy from transfer of data, Http application data is maintained secrecy introduce how to build efficient network security environment.

The confidentiality of transfer of data is an important content of network security, and in enterprise network information system, we can adopt SSH technology and software thereof to reach this object.

The English full name of SSH is Secure Shell.By using SSH, user can be encrypted the data of all transmission, and like this, " go-between " this attack pattern just can not achieve, and can prevent DNS and IP spoofing.The data of an extra benefit transmission are also had to be through compression, so the speed transmitted can be accelerated.SSH has a lot of function, and it both can replace Telnet, and can be again FTP, POP, even PPP provides " passage " of a safety.

SSH agreement is based upon the security protocol on application layer and transport layer basis, and it, primarily of following three part compositions, realizes the security mechanism of SSH jointly:

● transport layer protocol.This agreement provides the safety measures such as such as certification, trust and integrity check, can provide data compression function in addition.Under normal circumstances, these transport layer protocols are all based upon on connection-oriented tcp data stream.

● user authentication protocol layer.Be used for the authentication realized between server and client user, operate on transport layer protocol.

● connection protocol layer.Distribute multiple encrypted tunnel in some logical channels, it operates on user authentication layer protocol.

From client, SSH provides the safety verification of two kinds of ranks:

The first rank is the safety verification based on password.As long as user knows oneself account and password, just distance host can be signed in.The data of all transmission all can be encrypted, but can not ensure that the server that user is connecting is exactly the server that user wants to connect.Other server may be had to pretend to be real server, be namely subject to the attack of " go-between " this mode.

The second rank is the safety verification based on key.Need to rely on key, namely user is necessary for oneself and creates pair of secret keys, and Public key is placed on the server of needs access.If user is connected on SSH server, client software will send request to server, and request carries out safety verification with the key of user.After server receives request, under assigned catalogue, find the Public key of user, then the Public key that it and user send over is compared.If two key agreements, server just sends to client software with public-key encryption " inquiry " (challenge) it.Just again it can be sent to server with the private key deciphering of user after client software receives " inquiry ".

In this way, the password of oneself key must be known.But compared with the first rank, the second rank does not need to transmit password on network.The second rank is owing to encrypting the data of all transmission, so " go-between " this attack pattern is impossible (because he does not have the private key of user).

Use in the process of SSH user, should be noted that what SSH was made up of the software of client and service end, have two incompatible versions respectively: 1.x and 2.x.Can not be connected on the service routine of SSH 1.x by the CLIENT PROGRAM of SSH 2.x.Current, SSH technology Windows and Linux platform exchange visits and exchanges data time application very general.Ordinary circumstance is the SSH server by using under Linux, then uses the client software under the Windows such as Putty, Secure Shell Client to visit.

Along with the development of network and computer technology, data store and have become more and more important with the fail safe of exchanges data, integrality and consistency.In the network information security, the encryption technology of core is also applied to data storage and exchange.Meanwhile, in order to ensure correctness and the non repudiation of both sides' identity during network data exchange, visa system also reaches its maturity.How to ensure that on unsafe network, transmit data is safely difficult problems, and just greatly can ensure that the network user is transmitted and the fail safe of usage data based on the encryption of PGP (Pretty Good Privacy) mechanism and signature mechanism.

PGP is the email encryption software based on RSA public key encryption system.It not only can be read to prevent unauthorized person the data confidentiality of user, digital signature can also be added to mail thus receiver is be sure of mail is that desired people sends, let us can communicate with the people having never seen face safely, and is used for transmitting key without any need for the channel of maintaining secrecy in advance.

PGP have employed scrupulous key management---the Hybrid method of a kind of RSA and conventional cryptography, comprises mail digest algorithm, the front compression of encryption etc. for digital signature.It is powerful, and speed is very fast.The founder PhilZimmermann of PGP creatively combines the high speed of the convenience of RSA Public Key Infrastructure and conventional cryptography system, and have in digital signature and key authentication administrative mechanism and design very cleverly, thus make PGP become almost most popular public key encryption software kit.Wherein, RSA (Rivest-Shamir-Adleman) algorithm is a kind of Public Key Infrastructure based on " the impossible prime factor of large number decomposes hypothesis ".Be exactly briefly look for two very large prime numbers, one open to the world, do not tell anyone for one.Be called " PKI " and " private key ".These two keys are complementary, can decipher in other words, vice versa by the ciphertext of public key encryption with private key.

Because PGP employs IDEA proprietary algorithms, so use PGP to have the trouble of licence.People have found out some alternatives, and such as under Linux environment, people use GnuPG, and because GnuPG does not use IDEA proprietary algorithms, so use GnuPG without any restriction concerning user, and functionally it and PGP are the same.GnuPG uses rivest, shamir, adelman, and safe coefficient is higher.So-called rivest, shamir, adelman is exactly that each user has pair of secret keys: PKI and private key.Wherein, key is preserved by user, and PKI is then distributed to other people as much as possible by user, so that user communicates with other people.

Use GnuPG in fact very simple, provide a lot of order in linux system to carry out this software of assisted user and carry out encryption and decryption and digital signature, comprised and generate public/private keys to importing, the encryption and decryption of the derivation of, PKI, PKI, carry out signing etc. order to file.

In the process using PGP, should be noted that following Railway Project:

1. need the valid expiration date that should be used for determining to generate the algorithm of key, the length of key and key according to reality.

2. need user to be ensured the randomness of the double secret key generated by mutual rolling mouse, keyboard, otherwise, very likely by hack.

3. the safety of PKI is the core of PGP safety, and ripe encryption system must have a ripe key management mechanism supporting.The proposition of public key system is exactly that encryption key distribution in order to solve conventional cryptography system is difficult to ensure close shortcoming.Such as, but still there is safety issue in the issue of PKI, PKI is tampered, this may be leak maximum in public key cryptography system, because most of new hand can not find this point very soon.User must be sure of that PKI that you take belongs to it and looks that people belonged to.

4. maintaining secrecy of private key is also conclusive.Relatively public spoon, there is not the problem be tampered in private key, but there is the problem revealed.The way of PGP allows user be that the RSA private key of stochastic generation specifies a password.Only providing password and private key could be discharged use, itself is the same by the method privacy degrees and PGP of password encryption private key, so in fact first the safety issue of private key is maintaining secrecy to user password.Certain private key file itself is given away secrets also danger close, because just feel out your password by the method for exhaustion required for code breaker, have lost one deck fail safe after all though very difficult.Need most it is noted that will as any privacy your private key of preservation, do not allow anyone have an opportunity to touch it.

5. in the use procedure of reality, PGP software flexible can be applied to network data transmission by user, comprises each applications such as Email transmission, ftp file transmission.

Web communication is normally propagated on network with unencrypted form, and this is just likely arrived by illegal wiretapping, in particular for the password information of certification.In order to avoid these security breaches, just must be encrypted transmitting procedure.Transmitting to HTTP the agreement be encrypted is HTTP, it is the agreement of being carried out HTTP transmission by SSL, not only can be encrypted by the algorithm of Public key the fail safe ensureing transmission, but also can access authentication certificate CA be passed through, ensure that the server that client connects is not counterfeiting.SSL is a kind of encryption and authentication communication protocol of international standard, and this agreement all supported by general browser.

SSL (Secure Sockets Layer) is found out by Netscape company of the U.S. at first, becomes the standard of secure internet communication and transaction afterwards.Ssl protocol uses customer's certificate and the CA root certificate of communicating pair, allows client/server application can not to be communicated by the mode of eavesdropping with a kind of, establishes a safety, communication port trusty between communicating pair.It possesses following essential characteristic: information privacy, information integrity, mutually identify.This agreement mainly uses Hash coding, encryption technology, is no longer introduced these technology here.

In SSL traffic, first adopt asymmetric encryption exchange message, make server obtain the key of the symmetric cryptography that browser end provides, then utilize this key to carry out the encryption and decryption of information in communication process.In order to ensure that message is not tampered in transmittance process, the integrality that Hash coding guarantees information can be encrypted.

Server digital certificate is mainly presented to Web site or other need the server of authentication, to prove the identity information of server, equally also can issue client digital certificate for proving the identity of client.

Use the mode of Public key can ensure that transfer of data is no problem, if but the website of browser clients access is counterfeiting, and this is also a serious safety problem.This problem does not belong to encryption itself, but will ensure the correctness of key itself.Ensure that other obtained website Public keys are its correct key, but not the key of personation website, just must pass through an authentication mechanism, certification can be carried out to the key of website.Certainly, even without through certification, still can the safety of guarantee information transmission, just client can not be sure of that the server of accessing is not counterfeiting.If not the service in order to provide the aspects such as ecommerce very high to security requirement, generally do not need so strict consideration.

Here uses SSL to carry out the process communicated:

1. client initiates dialogue, consults to transmit cryptographic algorithm.Such as: symmetric encipherment algorithm has DES, RC5, Diffie-Hellman has RSA and DH, and digest algorithm has MD5 and SHA.

2. server sends server digital certificate to client.Such as: use DES-RSA-MD5 this to being combined into Serial Communication.Client can the identity of authentication server, determines the need of foundation communication.

3. user end to server transmits the key of this dialogue, reexamine the whether correct certificate issued by CA mechanism of digital certificate of server, after demonstrating the real effectiveness of server certificate, client generates and utilizes the key of this dialogue of the public key encryption of server to send to server.

4. server obtains the key of this communication with the private key deciphering of oneself.

5. the communication of both sides formally starts.

In the ordinary course of things, when client is the transmitter of security information, he does not need the authenticity of digital certificate authentication oneself identity, internet bank trade as normally used in us is movable, client needs the secret information of oneself (as account and password) to send to bank, therefore the server of bank needs to install digital certificate to show the validity of oneself identity, otherwise will make information leakage.Certainly, the B2B application very high to some security requirement, server end also needs to verify the identity of client, and when at this moment client also needs to install digital certificate to ensure to communicate, server can pick out the identity of client, and proof procedure is similar to the proof procedure of server identity.And under normal conditions, browser all can complete above-mentioned communication process by mutual mode.

user password is maintained secrecy

At present, Password Cracker adopts dictionary attack and brute force attack means mostly, if user cipher setting is improper, is very easily subject to the threat of dictionary attack.A lot of user likes the information such as the English name with oneself, birthday or account to carry out setting code, and like this, hacker can carry out decryption by the means of dictionary attack or social engineering.So suggestion user is in the process of setting code, the combining characters occurred in non-dictionary should be used as far as possible, and adopt the password set-up mode that numeral combines with character, capital and small letter combines, increase password by the difficulty of hack.And the mode also can use periodic modification password, making password regularly cancel, protects the login password of oneself.The reference principle specifically listing several setting security passwords is as follows:

● password length is at least 8 characters: the longer the better for password.If use MD5 password, it should have 15 characters at least.If use DES password, extreme length (8 characters) should be used.

● mixed upper and lower case letter, mixed letter and number, comprise the character (as &, $ and >) etc. beyond letter and number.

● select your password that can remember.

Secondly, some principles are also had to need to keep firmly in mind:

● only do not use word or numeral, do not use ready-made vocabulary, do not use the vocabulary in foreign language, also do not use hacker's term and personal information.

● do not reverse existing vocabulary: outstanding password code breaker always reverses common words, and the weak password that therefore reverses can't make it safer.

● do not put down your password, on all machines, all do not use same password yet.

In addition, we can also pass through some tool software, crack out expressly for attempting when known ciphertext, thus the safe coefficient of checking current password, a software as John the Ripper is exactly.

the correlation principle that linked network is maintained secrecy

Network management personnel, in daily work, especially should note the approach of divulging a secret of following several respects:

1. electromagenetic wave radiation is divulged a secret: computer network exists electromagenetic wave radiation when carrying out work, as long as there is special receiving system, just can receives radiation information thus cause and divulge a secret.Its radiation mainly contains four processes: connection line radiation, radiation monitor, main frame radiation, output equipment radiation.There is data to show, about 100 meters in open ground, just can receive radiation signal with audiomonitor.

2. secrets disclosed by net: the foundation of LAN (Local Area Network) and three grades of nets thereof, secondary net, one-level net progressively build up operation, it is the direction of current network application development, the computer that the application of these networks makes to be distributed in diverse location not commensurate is provided with the channel that information is transmitted, expand computer application scope, substantially increase operating efficiency and reduce administration cost, the file, the data that each user terminal can be utilized store in each computer.But while information sharing, there is a lot of leaks between main frame and user, between user and user, some unwarranted disabled users or molecule of stealing secret information to be soundd out or other ways enter network system and steal secret information by acting as fraudulent substitute for a person, for a long time.In addition, after networking, line channel branch is more, and the region of mail message is also comparatively wide, and the condition intercepting institute's carry information is just more convenient, the person of stealing secret information on any branched line of network or some nodes, terminal intercept, just can obtain the mail message of whole network.

3. operating personnel divulge a secret: divulging a secret of computer operator is the severely afflicated area of divulging a secret at present, and operating personnel likely cause from the following aspects and divulge a secret.(1) because ignorant is divulged a secret: as do not known, storage medium has the information can extracting reduction, is exchanged away by the storage medium once storing secret information, causes and divulge a secret; (2) confidential notions are strong, violate rules and regulations and divulge a secret: as computer break down after repair not according to established procedure, or process secret information on the computer that can not process secret information; The even cross-reference computer etc. had; (3) deliberately divulge a secret, this divulging a secret in order to other objects of individual interest or individual that be only a few people.This belongs to the behavior that be subject to discipline or law and investigate.

4. USB divulges a secret: the mobile memory with important informations such as confidential information, source code file, design drawings is connected on the computer of connection the Internet by staff, may just be stolen by spyware unconsciously.There is now the trojan horse that a kind of disguise is extremely strong, not only infect computer, also infect memory disc.The flash disk of user, once use on the computer infecting this program, will infect this virus.If this flash disk is used further to your office computer, will automatically in confidence the information reproduction on your computer on flash disk.When next time, this dish was inserted the computer of online by again, automatically will send the information on dish to the Web specify place.Whole process is secret, automatically completes, and user is difficult to discover.
