Abstract

The present invention discloses an encryption algorithm realizing method and system. The method comprises the steps that a first terminal generates a first secret key pair according to a first setting rule; a first public key is sent to a second terminal; the second terminal generates a second secret key pair according to the first public key; a second public key is sent to the first terminal; the first terminal encrypts first data by using a first private key according to a second setting rule so as to generate a first ciphertext, generates a first ciphertext decryption rule according to the second setting rule, generates a data check packet according to the first ciphertxt, generates a data check packet ciphertext according to the first private key and the data check packet, and sends the first ciphertext and the data check packet to the second terminal; the second terminal decryptes the data check packet ciphertext by using the first public key so as to obtain the data check packet, and checks whether the first ciphertext is valid; if the first ciphertext is valid, a decryption rule is obtained, a local secret key is generated according to the second private key and the first public key, and the first ciphertext is decrypted by using the local secret key and the decryption rule. According to the encryption algorithm realizing method, information transmission reliability and security are improved.

Description

technical field [0001] The embodiment of the present invention relates to computer data processing technology, and in particular to a method and system for implementing an encryption algorithm. Background technique [0002] With the rapid development of computer network technology and the wide application of mobile banking APP (Application, application program), the safe transmission of information is particularly important. In order to ensure the reliability and authority of information in the process of processing, storage and transmission, Data encryption technology is widely used. [0003] At present, encryption techniques are generally divided into two categories, "symmetric" and "asymmetric". Symmetric encryption technology uses the same key for encryption and decryption. This encryption technology is widely used today. For example, the DES encryption standard is a typical "symmetric" encryption algorithm. Asymmetric encryption technology uses two different keys for ...
