Self-certified Signcryption Scheme with Proxy Re-encryption Property
摘要
Abstract
By analyzing Yu Huifang's self-certified signcryption scheme, this paper finds that the proxy can recover the private key of the original signcryptor, and proposes a self-certified signcryption scheme with the character of proxy re-encryption based on bilinear mapping. It makes use of a semi-trusted proxy to realize the transparent conversion between the different de-signcryptor's identities of the signcryption on the same plaintext. Compared with another scheme, the scheme proposed can eliminate the certification management in the traditional public key cryptosystem and the key-escrow in the identity-based system, and it has advantages of high security, short key, low computing complexity and communication costs.关键词
