Abstract:

This paper presents an encryption broadcast scheme based on secure frameproof codes.Using the secure frameproof codes,an (n,k)-resilient encryption broadcast scheme is constructed,which is applicable for an especially encryption broadcast situation where the privilege user set has an upper bound.The scheme can accomplish the broadcast task if the broadcast center transmits the encrypted message one time and the user stores only one key.And when the privileged user set recovers the decryption key,the broadcast center need not broadcast any message.The broadcast system bandwidth requirement and memory complexity are less than the existing schemes.

Key words: encryption broadcast;secure frameproof code;resilient encryption scheme
