Abstract

The invention provides a system, encryption method and device as well as decryption method and device for broadcast communication. The encryption method comprises the following steps: determining at least one authorized user; determining an identity of each authorized user; setting a public key; generating a private key of each authorized user according to the public key and the identity of each authorized user; encrypting a broadcast file by using the public key to generate a ciphertext; and broadcasting the ciphertext to ensure that each authorized user decrypts the ciphertext according to the corresponding identity and private key to obtain a cleartext. According to the system, encryption method and device as well as decryption method and device for broadcast communication provided by the invention, the security of broadcast communication can be improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a broadcast communication system, an encryption method and device, and a decryption method and device. Background technique [0002] Broadcast communication is to send information to various users through broadcasting. At present, broadcast communication is becoming more and more common in network communication. [0003] In the prior art, any user can receive the information broadcast in the broadcast communication, and these information are all unencrypted information, and any user can obtain the information transmitted in the broadcast communication. It can be seen that the broadcast communication in the prior art less secure. Contents of the invention [0004] Embodiments of the present invention provide a broadcast communication system, an encryption method and device, and a decryption method and device, which can improve the security of broadcast communication.
