摘要/Abstract

摘要： To give concurrent consideration both
the efficiency and the security (intensity of intractable problem)
in the standard model, a chosen ciphertext secure identity-based
broadcast encryption is proposed. Against the chosen ciphertext
security model, by using identity (ID) sequence and adding
additional information in ciphertext, the self-adaptive chosen
identity security (the full security) and the chosen ciphertext
security are gained simultaneously. The reduction of scheme's
security is the decisional bilinear Diffie-Hellman (BDH) intractable
assumption, and the proof of security shows that the proposed scheme
is indistinguishable against adaptive chosen ciphertext attacks in
the standard model under the decisional BDH intractable assumption.
So the security level is improved，and it is suitable for higher
security environment.
