Abstract:
1. A method for implementing encryption and transmission of information, characterized in that the following steps are performed when a sender sends information to a receiver: allowing a client of the sender to encrypt the information by using only a unique identifier of a receiver identity itself as a public key, the information sent from the sender to the receiver being SMS information or MMS information; allowing the sender to send the encrypted information to the receiver; and allowing the receiver to receive the encrypted information, and allowing a client of the receiver to perform decryption by using a user private key; wherein the client of the receiver is allowed to obtain the user private key by one-off registration, and the user private key matches with the unique identifier of the receiver identity; the step of allowing the client of the receiver to obtain the user private key by one-off registration comprises: allowing the client of the receiver to apply for a registration to a registration server using said unique identifier of a receiver identity; using the registration server to perform authentication on said unique identifier of the receiver identity, and to send said unique identifier of the receiver identity of the receiver which passes the authentication to a private key generation server; using the private key generation server to generate the user private key according to the unique identifier of the receiver identity, to form a pair of keys consisting of the user private key and the unique identifier of the receiver identity, and to send the user private key to the registration server; using the registration server to return information of registration success to the client of the receiver, and to send the user private key to the client of the receiver; wherein the receiver is a mobile terminal, and the unique identifier of the receiver is a mobile terminal number of the receiver or a network communication number of the receiver, or the receiver is a PC or other device connected to a network in a wired or wireless manner, and the unique identifier of the receiver is a network communication number of the receiver; there is no need of negotiating with other communication entities comprising a management server to obtain a public key.
