Integrated dynamic cipher generating device

Abstract

The invention provides an integrated dynamic cipher generating device. The device comprises an information manager, an information reservoir, a key presser, a cipher generator and a display; the information reservoir comprises an encryption part, multi-group cipherers and a decryption part, the cipherer comprises a dynamic cipher storer and a dynamic cipher counter; the information manager is connected with the information reservoir, the information manager sends confidential information to the information reservoir, the confidential information is transferred to the dynamic cipher storer after the encryption of the encryption part; one end of the key presser is connected with the information reservoir, and the other end is connected with the cipher generator; the key presser transmits the selected confidential information in the dynamic cipher storer to the cipher generator after the decryption of the decryption part; the display is connected with the cipher generator, and the dynamic cipher generated by the cipher generator is displayed through the display. The invention further provides a method for generating the dynamic cipher through the integrated dynamic cipher generator. A plurality of cipherers are integrated, the carry is simple, the security is high, and the use is simple.

Description

technical field [0001] The invention relates to the technical field of electronic ciphers, in particular to an integrated dynamic cipher generating device. Background technique [0002] With the advancement of technological networks, user identity authentication is becoming more and more important, and ciphers or digital authenticators required for confidential or private data become necessary. Now, each unit or each bank has its specific cipher or digital authenticator, but the cipher or authenticator is not interoperable, and the public needs to carry multiple ciphers or authenticators at the same time, which is very inconvenient; Generally, it needs to be plugged into the PC interface, and it is easy for people to forget to unplug it and take it away after use, resulting in loss and potential safety hazards; some authenticators need to install a special driver, and the driver will choose the PC, which is difficult After successful installation on each machine, this type ...

Problems solved by technology

Now, each unit or each bank has its specific cipher or digital authenticator, but the cipher or authenticator is not interoperable, and the public needs to carry multiple ciphers or authenticators at the same time, which is very inconvenient; Generally, it needs to be plugged into the PC interface, and it is easy for people to forget to unplug it and take it away after use, resulting in loss and potential safety hazards; some authenticators need to install a special driver, and the driver will choose the PC, which is difficult After successful installation on each machine, this type of authenticator can only be operated on a specific PC with a driver program, and cannot be used anytime and anywhere; moreover, too many ciphers or authenticators and debit cards often cause users Matching errors in a hurry, resulting in the failure of network transactions
