Abstract :
When some one wants to sign a message for a designated group in distributed networks, he can sign the message one by one for each member in designated group, but the efficiency is very low. In this paper, we propose a new type of signature, broadcast group oriented signature, to make the signer easier. The signature has the properties: is easy to manage public keys; has no characteristic of key escrow; nobody outside the designated group can verify the signature. The signature is very fit for the condition that the signer only has limited computational resource or bandwidth and each member in designated group is asked to independently verify the signature
