The intelligent encryption method that a kind of computerized information of the present invention transmits is to adopt following operating procedure:
The transmitting terminal of computerized information is that A(includes encryption key and decruption key), the receiving terminal of computerized information is that B(includes encryption key and decruption key),
Step 1: the intelligent DES key generation apparatus of the transmitting terminal A of computerized information generates DES key;
Step 2: the intelligent RSA key of the receiving terminal B of computerized information generates RSA key pair to generation device;
Step 3: the DES key that intelligent DES cipher key encryption means generates intelligent DES key generation apparatus is encrypted, generates the key of des encryption; Intelligence RSA key decryption device generates RSA key to being encrypted to intelligent RSA key to generation device, generates the public encipherment key of RSA;
Step 4: the intelligent information of the transmitting terminal A of computerized information receives and dispensing device obtains through intelligent RSA key decryption device public encipherment key, and encrypts DES key in intelligent DES cipher key encryption means, forms new ciphertext;
Step 5: receive with dispensing device new ciphertext is sent to digital signature device by intelligent information, generate the information that needs signature in digital signature device;
Step 6: the signing messages generating in digital signature device with DES secret key encryption in the intelligent DES cipher key encryption means of the transmitting terminal A of computerized information, then in intelligent DES cipher key encryption means, form final ciphertext together with new ciphertext, intelligent information reception and dispensing device mail to the receiving terminal B of computerized information;
Step 7: the intelligent information of the receiving terminal B of computerized information receives and dispensing device is receiving after the final ciphertext of intelligent DES cipher key encryption means generation, send in intelligent RSA key decryption device, in intelligent RSA key decryption device, DES key first decrypts the DES key in final ciphertext with the decruption key of oneself, and the DES secret key decryption recycling in final ciphertext goes out expressly and signing messages;
Step 8: intelligent information receives and dispensing device sends the plaintext that decrypts and signing messages to intelligent DES cipher key encryption means, in intelligent DES cipher key encryption means, public-key cryptography and the decruption key of oneself carry out authentication to signing messages, then intelligent DES cipher key encryption means is done after suitable processing signing messages, the digital signature information that forms again oneself sends, and the transmitting terminal A of simultaneous computer information and the receiving terminal B both sides of computerized information all delete DES key.
The present invention is fast to the encryption/decryption speed of file, in the ciphertext of transmission, carry the DES key of rsa encryption, reduce the risk that key is divulged a secret in transmitting procedure, effectively prevent the threat of network monitoring to information security, there is the function of signature and authentication owing to having adopted RSA Algorithm simultaneously, communicating pair can be issued the digital signature information of oneself mutually the other side for retaining and authentication, and key management is also convenient, oneself only need be maintained secrecy and manage to each communication object RSA decruption key just.
