Detailed Description
The invention is further described with reference to the following figures and detailed description.
A user's logistics receiving address information is encrypted and then pasted on the surface of a mail package in a two-dimensional code mode, only a special reading device with a decryption key can read the two-dimensional code and decrypt to obtain a mail address information plaintext, the mail address information plaintext is divided into a plurality of parts according to logistics address grades, as shown in figure 1, different keys are adopted for hierarchical nested encryption, and in the whole logistics mailing process, different middle sorting or terminal decoding modules can only decrypt respective address parts. The logistics address level is established according to the geographical area and adopts a tree structure.
The typical working process of the method is as follows:
(1) before a user sends a mail (such as after shopping on the internet), a software tool locally generates a random verification code, wherein the verification code can be a number, a character, a Chinese character or a pattern, the verification code is divided into two parts VA and VB, and the user stores the verification code and sends the verification code to a mail receiver (the mail receiver can also be the user) through a network or other modes for later authentication. Meanwhile, the software tool generates hierarchical nested encrypted address information according to the verification code and the input mailing address, the address is divided into a plurality of levels from large to small, such as country, province, city, district and terminal information, wherein the terminal information comprises the terminal address (such as a district, a building number and a room number), contact information (such as a contact telephone and a name of a user) and the verification code. When generating hierarchical nested encrypted address information, terminal information A is used first0Upper address A of1Corresponding public key encrypts end information to obtain C0Reuse of A1Upper address A of2Corresponding public key handle A1Encrypted to obtain C1Then using A2Upper address A of3Corresponding public key handle A2Encrypted to obtain C2By analogy, the address A is finally setn-1Upper address A of (e.g. country)nCorresponding (e.g. global) public key holder An-1Encrypted to obtain Cn-1And a isnAnd Cn-1、Cn-2、...、C1Together form a, which is not encrypted because the top-level address An sensitivity is negligible;
(2) the user transmits the A to a sender (such as a merchant), and the sender converts the A into a two-dimensional code by using a tool and pastes the two-dimensional code on the surface of a package to be delivered to a transmitter (such as a logistics enterprise);
(3) the processing equipment of the conveying side firstly scans the two-dimensional code on the surface of the package to obtain AnAnd Cn-1Then has AnDecryption C of decoding module of corresponding private keyn-1Obtaining An-1And transporting the package to An-1Address to An-1After the address, has An-1The decoding module of the corresponding private key decrypts through the decryption Cn-2Obtain a Secondary Address An-2Thereby, it is possible to obtainAnd so on until the package is shipped to address A1；
(4)A1The address submitter uses a dedicated reading device which, by having a corresponding A1The decoding module of the private key corresponding to the address decrypts through the decryption C1The method comprises the steps of obtaining terminal information of a mail receiver, wherein a contact telephone contained in the terminal information can only be used for a presenter to dial or send a short message to the mail receiver (the contact telephone presenter is not visible specifically) through a special reading device, the presenter finds the mail receiver according to a terminal address, proves that the sender is a legal presenter of a package by showing a verification code VA, and can be used for the recipient to verify that the receiver is the legal presenter of the package before opening a door, and meanwhile, the presenter can verify that the current receiver is legal through the verification code VB.
In the above steps, the encryption of the logistics address adopts an asymmetric encryption algorithm, that is, the encrypted key and the decrypted key are different and cannot be derived from each other, wherein the encrypted key is public and is called a public key, and the decrypted key is secret and is called a private key. When the asymmetric cipher algorithm is used for encryption, a random number with a fixed length is added to an encrypted plaintext, then the encrypted plaintext is encrypted, and after decryption, the random number added at the last is removed to obtain a real plaintext.
In the above step, the verification code is optional, that is, the user may let the software tool generate the verification code in step (1) and use it for the bidirectional authentication between the presenter and the mail receiver in step (4), or may select only the VA part or VB part of the generated verification code and perform the unidirectional authentication between the presenter and the mail receiver in step (4), or may select not to generate the verification code and not perform the authentication in step (4).
In step (4), as shown in fig. 2, the special reading device used by the submitter may be composed of a two-dimensional code scanning module, a decoding module, a communication module, an input module, a screen display module, and a control processing module. The two-dimensional code scanning module is used for scanning the two-dimensional code, the decoding module is used for decrypting information obtained by scanning by using a private key of the decoding module, the communication module is used for communicating with a mobile phone and a fixed telephone of a mail receiver, and the input module, the screen display module and the control processing module are respectively used for inputting, displaying information and controlling the whole. The dedicated reading device has fingerprint or password protection to ensure that its user is the intended user of the transmitting party.
And (3) safety analysis:
(1) because the mail posting address is encrypted locally by a software tool by using the public key corresponding to each level of corresponding address, an unauthorized person (including a sales platform) cannot decrypt the address information of the mail receiver.
(2) Because the mail posting address adopts hierarchical nested encryption, no matter the sorting equipment or the sorter in the logistics process or the deliverer of the terminal, only the information which is required to be obtained by each logistics service can be obtained, but other address information which is not required to be obtained cannot be obtained. Specifically, the sorting equipment or the sorter can only obtain the address of the next level of the address where the sorting equipment or the sorter is located, but cannot obtain the address information of the next level, and the sorting equipment or the sorter cannot decrypt the mail address information beyond the address range where the sorting equipment or the sorter is located (for example, the sorting equipment or the sorter in Henan province cannot decrypt the address information mailed to Hebei province).
(3) Because the private key in the decoding module can not be exported from the decoding module through normal operation or illegal means once being written in, even if many decoding modules have the private key corresponding to the same address, logistics company personnel can not copy the decoding module or obtain the private key to bypass the decoding module to carry out the decryption operation of the mail address.
(4) Since the special reading device used by the submitter of the terminal address cannot display the contact telephone of the mail receiver and can only dial or send short messages, the contact telephone of the receiver cannot be revealed to anyone.
(5) Because the verification code is randomly generated by the software tool locally by the user, the receiver can verify that the mail delivered to the door is legal logistics personnel by using the VA part in the verification code, so that illegal personnel can be prevented from cheating the trust of the receiver into the house or other private spaces by the logistics personnel, or cheating by using counterfeit packages; by using the VB part in the verification code, the submitter of the terminal address can verify whether the person receiving the mail is a legal mail receiver, so as to avoid falsely claiming the mail.
(6) The encryption algorithm of the address information is encrypted by adopting an asymmetric encryption algorithm, and since addresses at all levels are possibly exhausted, such as province and city addresses, an illegal attacker can acquire real address information by utilizing exhaustion attack, namely, a public key is used for encrypting all possible addresses and comparing the addresses with the encrypted addresses to be attacked, but in the previous step, when the asymmetric encryption algorithm is used for encryption, a random number with a fixed length is added after the encrypted plaintext, then encryption is carried out, the random number added at the last is removed after decryption to acquire the real plaintext, so that the attacker cannot utilize the public key to encrypt and compare the possible address information to acquire the real address information, and the encryption of the address information can resist the previous exhaustion attack.
(7) Because the decoding module must be authenticated by relevant national departments or a third-party trust center and has a unique number, the decoding module can be ensured to be only taken by legal logistics companies or personnel with professional qualifications. And because the decoding equipment can only carry out decryption operation and can not derive the private key, the private key can not be revealed.
(8) Sensitive information evidences contacted by the decoding modules can be stored in the remote server at regular time, so that if a mail posting address of a user is leaked, which decoding module is contacted with the information can be tracked according to the address, and related logistics personnel can be tracked.
To illustrate that the method of the present invention can be implemented, a specific implementation in a home shopping express scenario is shown in fig. 3.
The third party trust center formulates address lists of all levels of express delivery addresses except terminal addresses according to three levels of provinces (or direct prefecture cities), cities (or regions) and streets, wherein the province (or direct prefecture cities) level addresses comprise: hebei province, Henan province, Jilin province, Shandong province, Shanxi province, Beijing City, Shanghai City, etc., and the city (or district) level address includes: zhengzhou city, three gorges city, Anyang city, Shenyang city, Dalian city, Beijing Haishen district, Beijing Chaoyang district, etc., and the block level addresses include: the third-party trust center generates a public and private key pair corresponding to each address according to an RSA asymmetric cryptographic algorithm with 1024-bit cipher text length for each address, and finally, the third-party trust center issues address lists at all levels and corresponding public keys thereof.
The express company submits the decoding module to a third-party trust center and declares the working address of the decoding module, and the third-party trust center injects the unique number and the private key corresponding to the working address of the decoding module into the decoding module after authenticating that the decoding module meets the safety requirement of the third-party trust center. For example: if the address of the decoding module is Beijing city, it has a private key corresponding to Beijing city, and it can decrypt and obtain the addresses of the areas in Beijing city in the logistics address by using the private key.
The user appoints the mail address, the input end address and the contact information through the address lists of all levels and selects whether to need the verification code, the tool software generates the mail address information of hierarchical nested encryption, and simultaneously the tool software displays the generated verification code to the user. The user stores the verification code, if the user does not receive the mail, the verification code is sent to the mail receiver through the network or other ways, and the user sends the encrypted mail address information to the merchant. The encrypted mail address information has the following format: the first level address number is a country number (no encryption, 1 byte), the second level address number (a number in province or the city of the direct jurisdiction) is encrypted by a public key corresponding to the first level address after being added with 128 bits of random numbers, the ciphertext is 1024 bits and occupies 128 bytes, the third level address number is similar to the fourth level address number in encryption, the tail end information is encrypted by a public key corresponding to the fourth level address (the number in the street) after being added with 128 bits of random numbers, the ciphertext is 1024 bits and occupies 128 bytes, wherein the tail end information is not more than 80 Chinese characters, letters and numbers (maximally 160 bytes) and consists of 4 parts, the first part is address detailed information, the second part is mail receiver names (not more than 10 Chinese characters and maximally 20 bytes), the third part is mail receiver numbers (11 decimal digits, 11 bytes), the fourth part is verification codes (4 bytes, 1-2 bytes are VA part and 3-4 bytes are VB part), so the total length of the encrypted mail address information is 513 bytes.
The merchant converts the encrypted mail address information into a two-dimensional code by using a downloaded two-dimensional code generating tool, and attaches the two-dimensional code to the surface of the package of the user commodity. Wherein the two-dimensional code may be encoded using a QRcode that is capable of holding about 2 kbytes of information and thus sufficient to hold encrypted mail address information.
After receiving the mail given by the merchant, the express company firstly scans the two-dimensional code, obtains a first-level address according to a first byte in the scanned information, decrypts a ciphertext of a second-level address by using a decoding module with a private key corresponding to the first-level address to obtain the second-level address, and sends the mail to the second-level address. The sorter or the sorting equipment of the second-level address (such as Henan province) head office obtains the third-level address by scanning the two-dimensional code and decrypting the 2 nd to 129 th bytes in the scanned information by using a decoding module (such as a decoding module with a Henan province private key) with a private key corresponding to the second-level address and removing the 16 byte (128 bits) random number attached to the tail, and so on until the street terminal courier scans the two-dimensional code on the mail by using a held special reading device, the decoding module in the special reading device has the private key corresponding to the street, so that the 386 rd and 513 th bytes in the scanned information are decrypted to obtain the terminal information. The special reading device can only display the first, second and fourth parts of the terminal information, and the third part (the mobile phone number of the mail receiver) can only be dialed or sent with short messages and cannot be seen through the display screen of the special reading device.
After the terminal courier finds the address of the mail receiver, the mail receiver can verify the validity of the terminal courier through the VA part of the inquiry verification code, and the terminal courier can verify the validity of the mail receiver through the VB part of the inquiry verification code.
The method for protecting the password realizes automatic invalidation and password protection when a decoding module is lost or people try to continue using illegally after leaving the work by a method of feeding the dog.
And the decoding module needs to upload audit information at regular time, otherwise, the decoding module fails automatically.
The decoding module has a unique key (which can be composed of multi-stage keys) of the decoding module, and regular or emergency updating of the key is realized.
