Abstract
In most parctical circumstances,there isn't an authority which can be trusted by all members, so this paper proposed a threshold scheme without a trusted party. This paper constructed the scheme on the basis of Shamir' s perfect secret sharing system and used Lagrange interpolation to restore the secret. In this scheme, monitor agency could easily reconstruct session key when few escrow agency could't cooperation. It not only effectually prevented form law enforcement decryptor too much power, but also solved effectively the problem of once monitor, monitor for ever". Besides, every escrow agency could verify correctness of the secret shadow that it escrowed. It cometo a conclusion that the new designed scheme is more perfect and more security.关键词
