摘要：

Certificateless cryptography solves the key escrow problem inherent in identity-based cryptography. This paper first presents a practical model for certificateless threshold decryption scheme which avoids both the single point of failure in the distributed networks and the inherent key escrow problem in identity-based cryptosystem. Based on the idea of [9], The paper also introduces the first certificateless threshold decryption scheme that is IND-CCA secure against chosen ciphertext attack in the standard model.
