Key exists in pairs with private cipher key, if be encrypted to data with public-key cryptography, only could be solved with corresponding private cipher key
It is close；If be encrypted with private cipher key pair data, then only could be decrypted with corresponding public-key cryptography.Because encryption is conciliate
It is close to use two different keys, so this algorithm is referred to as asymmetric-key encryption algorithm.
Asymmetric-key encryption algorithm realizes that the basic process that confidential information is exchanged is：Party A is (in embodiments of the present invention,
Can be target access) generate a pair of secret keys and disclose therein one to other data interaction sides as public-key cryptography；
Obtain Party B's (in embodiments of the present invention, can be terminal device) of the disclosure key is carried out using the key to confidential information
Party A is then forwarded to after encryption；Party A is decrypted again with the information after the corresponding private cipher key pair encryption for oneself preserving.
