摘要: 利用中国剩余定理的知识提出一种在参与者中共享多个秘密的方案,每个参与者选择自己的秘密份额。方案中用到RSA密码体制,该体制在密码学领域中具有广泛的应用性。利用该体制分发者能够确保各个参与者所选的秘密份额不同,使得秘密共享过程顺利进行。方案的安全性基于大整数分解的困难性,是一个较为实用的多秘密共享方案。

Abstract: This paper proposes a multi-secret sharing scheme, where the knowledge of Chinese remainder theorem is used. Each participant can select his own secret sharing. In the scheme, the RSA cryptosystem is used, and the system has a wide application in the cryptography field. The distributor of the system can ensure that each participant selects different secret sharing, and it is for the purpose that the secret share can progress smoothly. The security of the scheme is based on the difficulty of large integer number factorization. It is a useful multi-secret sharing scheme.

Key words: Chinese remainder theorem, RSA cryptosystem, multi-secret sharing
