摘要:

In this work, under assumption that all the eigenvalues of the linear nominal discrete time‐delay system lie within a specified circular region, a sufficient condition is proposed to preserve the assumed property when the structured parameter perturbations are added into the linear nominal discrete time‐delay system. By mathematical analysis, the presented criterion is proved to be less conservative than the existing one reported in the literature.

摘要:

We propose an undeniable (t, n) threshold signature scheme with cheater identification. The proposed scheme has the following features: (1) no trusted third party is required for key generation; (2) no additional interactive protocol is required for the generation of the group's public key; (3) anytmembers can cooperatively sign a message with the assistance of a secure cryptographic module designated by hardware; and (4) the verifier can verify the group signature by only knowing the group's public key; it is not necessary to know the participating signers involved. The proposed scheme also provides capabilities against cheating tricks plotted by signers in the key generation and group signature generation phases.
