Description

A kind of dynamic cipher method and system

Technical field

The present invention relates to field of encryption, it is particularly related to a kind of dynamic cipher method and system.

Background technology

At present, mostly the auth method that provides of each service organization is to provide a static password for the client.The user carries out authentication by this static password between service organization and the user when accepting the electronics automated transaction service that service organization provides, finish the transmission of transaction or commodity.But, the verification method of this identity is very dangerous, because this static password is easy to be decoded by other people, and the method for decoding this static password much also is easy to, as: adopt computer technology intercepted data, artificial theft, the means such as deceiving the robber of colluding from both within and without to obtain user's static password, the false claiming customer deposit, this type of incident often is reported in media.This uses electronically to be engaged in social and economic activities to people and has brought very big risk, brought the machine adverse influence also for simultaneously the development of the electronics automated transaction (as ecommerce, E-Payment etc.) that is rising, hindered these industries and developed to darker farther direction.

The digital certificate encryption technology can be carried out encryption and decryption, digital signature and signature verification to the information of transmission over networks, guarantee to transmit confidentiality, the integrality of information on the net, and the authenticity of transaction entity identities etc., the non-repudiation of signing messages, thereby the fail safe of guarantee network application.Digital certificate has strengthened the fail safe in the communication process to the full extent, but need storage medium (storage cards of USB or other media) could preserve use, " based on the diploma system of USB flash disk ", the basic ideas of this device authentication system are: Store Credentials information in USB flash disk, accomplish that certificate walks with oneself, but this equipment has increased the cost of whole Verification System, if certificate is lost, consequence is still as above-mentioned serious.And certificate popular in the employing industry will be paid high usage charges, installs also inconveniently, must each user all carry out the installation of software in computer, difficult well imagining for the not high common user of computer level.

Occurred dynamic password mechanism at present, dynamic password (Dynamic Password) also claims disposal password (One-time Password).Dynamic password is the password of change, and its change derives from the operational factor that produces password and changes.The generation factor of dynamic password generally all adopts two operational factors (Two Factor): one is user's privately owned password.The identification code of its representative of consumer identity is changeless.Its two, be the change factor.Change the continuous variation of the factor just, just produced the dynamic password of continuous change.Adopt the different change factors, formed different dynamic cipher verification technology: based on time synchronized (TimeSynchronous) authentication techniques, based on asynchronous (Challenge/Response Asynchronous) authentication techniques of event synchronization (Event Synchronous) authentication techniques and challenge/response mode.

Based on the time synchronized authentication techniques be the passage time as the change factor, generally with 60 seconds as the variation unit.So-called " synchronously " is meant that the password that user cipher card and certificate server are produced in time must be synchronously.The method for synchronizing time here is not with " time system " technology, but with " sliding window " technology.When figure is the client terminal access system, based on the verification process of time synchronized.The terminal of user side and the clock synchronization of server end, the dynamic password that will utilize user terminal to generate dynamic password and server when the user accesses to your password is complementary, otherwise can not be by the cipher authentication of server, this system needs the great number cost of user terminal equally.

A kind of dynamic data cipher-code input method and the device that are disclosed in the Chinese invention patent 03106069.2, its method is: offer the data saltus step unit that the operator imports selection and be in the dynamic change state automatically, so that the different contents of confirming constantly of operator are decided with the represented implication in data saltus step unit; Input whole passwords up to the operator, the total data of operator input is read in and preserved in system, and the data of reading in and preserving are carried out uniqueness judge, when the data of reading in and preserving when system were unique, this unique data was the operator and inputs password.But this method is not carried out real dynamic operation to information such as passwords, has just done the processing of saltus step on inputting interface, and fail safe is not high.

Chinese invention patent 00109820.9 has disclosed a kind of method and corresponding electronic installation that adopts the confirming payment of dynamic password, send the on the same day sign indicating number that at random produce with direct to trade company or bank to the user through retransmission center by the dynamic cipher verification device, the user imports the common dynamic password of forming of heart sign indicating number that above-mentioned sky sign indicating number and trade company or bank give the user in advance to trade company or bank, supplies trade company or bank to check.But this method needs the third party to participate in, and need to notify the user password of today through modes such as mail or mobile phone short messages, the work of encrypting is finished the just simple password that receives of user by service end entirely, caused the possibility of further divulging a secret like this, and use and inconvenience, the user needs to obtain password from the dynamic cipher verification device through transmitting in each transaction, and the acquisition of password is passive from the user.

Increase functional modules such as the reporting the loss of dynamic password card, rule maintenance.

Further, can also adopt migration technology for the confidentiality of strengthening dynamic password.Migration technology is exactly to carry out selection side-play amount when synchronous the user according to dynamic password card and dynamic password device, when the client sends the cryptographic check request, the index of system prompt must be recombinated according to the predefined side-play amount of client, and the pairing cipher symbol of index sequence of this reorganization is only the login password (if exceeding then circulation) that this client should import.For example: the password string of client A as shown in Figure 1; The unification of setting side-play amount to the right is 1; System prompt index sequence is: 20,1,3,4, if the importer does not know that the direction or the side-play amount that are offset are exactly directly to import: rej8, the user this time true index sequence of login should be: 1 (20+1 circulates), 2 (1+1), 4 (3+1), 5 (4+1).Hence one can see that password that this client this time lands should be eu8u.The unification that also can set simultaneously side-play amount left is 1; System prompt index sequence is: 2,3,5,6, if the importer does not know that the direction or the side-play amount that are offset will directly import: uju6, but the user this time true index sequence of login should be: 1 (2-1), 2 (3-1), 4 (5-11), 5 (6-1).Hence one can see that password that this client this time lands should be eu8u.

Set different side-play amounts: when the client sends the cryptographic check request, the index of system prompt must be recombinated according to the predefined side-play amount of client in step-by-step, and the index sequence of this reorganization is only that this client should input lands password (if exceeding then circulation).For example: the cipher symbol matrix of client A as shown in Figure 2; Set unified for behavior base cycle offset 1,2,3,4 to the right; The password that generates is: abty, the dynamic password device then points out the user to import the index sequence: 15 (the 1st row the 5th row), 15 (the 1st row the 5th row), 42 (the 4th row the 2nd row), 51 (the 5th row the 1st row), if the importer does not know that the direction or the side-play amount that are offset will directly import: eequ, and the true sequence that the user this time lands should be: 11 (the 1st the row constant, 1 row are moved in the circulation to the right of the 5th row), 12 (the 1st the row constant, 2 row are moved in the circulation to the right of the 5th row), 45 (the 4th the row constant, 3 row are moved in the circulation to the right of the 2nd row), 55 (the 5th row is constant, and 4 row are moved in the circulation to the right of the 1st row).Hence one can see that password that this client this time lands should be abty.Equally also can move to left.

Be set to classify upwards cycle offset 1,2,3,4 of basis as when moving; The password that generates is: abty, the dynamic password device then points out the user to import the index sequence: 21 (the 2nd row the 1st row), 32 (the 3rd row the 2nd row), 25 (the 2nd row the 5th row), 45 (the 4th row the 5th row), if the importer does not know that the direction or the side-play amount that are offset will directly import: fljt, and the user this time true sequence of login should be: 11 (the 2nd row moves 1 row to cocycle, the 1st row are constant), 12 (the 3rd the row to cocycle move 2 the row, the 2nd row are constant), 45 (the 2nd the row to cocycle move 3 the row, the 5th row are constant), 55 (the 4th row moves 4 row to cocycle, and the 5th row are constant).Hence one can see that password that this client this time lands should be abty.Adopting uses the same method also can circulate downwards mobile.

As shown in Figure 4, for numerous application systems towards the interior employee, employing the present invention independently dynamic cipher system transforms the authentication of all application systems of inside, adopts the relatively low scheme of this cost, can solve the problem of the authentication of inner single-sign-on.The dynamic password device can produce different dynamic passwords according to event driven mode when enterprises is used, index on the user side dynamic password card can adopt letter or other optional sign, just play the effect of index, and the value of cipher symbol also is unrestricted, kind (the letter of the cipher symbol that on same password card, adopts, other symbols such as punctuate) many more safe more, user's input terminal can be for joining the computer of network, also can be other platforms that transactional services side provides, as ATM etc.

Beneficial effect of the present invention is, has saved the cryptographic calculations device of user side in the existing dynamic cipher system, has reduced cost and has guaranteed suitable fail safe, and cryptographic system algorithm diversity is strong, meets the demand of usefulness more.

Above embodiment only is used to illustrate the present invention, but not is used to limit the present invention.
