Abstract :
In order to resolve the secure distribution problem in Email system, a novel encryption scheme with wildcards is proposed, which adopts the Identity-based public key cryptography technology. This new scheme has private key size linear with the identity depth and is built in standard model. Furthermore, the scheme is proved secure against chosen plaintext attack under Bilinear Diffie-Hellman Inversion (BDHI) assumption.
