摘　　要：基于对运算,利用短签名,建立了一个指定验证方的(t,n)门限验证签名方案。该方案不需要专门操作来完成密钥分片,更适合每个节点只有自己的公钥和对应的私钥的动态网络环境,比如Adhoc的组网方式。并且该方案可扩展为广义的指定验证方的门限验证签名方案,在计算性Diffie-Hellman问题困难假设下利用随机预言模型证明了该方案的安全性。Based on bilinear pairings and short signature, a signature scheme for specified threshold verifiers is proposed. The proposed construction does not require special process to distribute secret key, so the scheme is more suitable for dynamic network environment which per node have nothing but publci key and private key, such as Ad hoc. Simultaneously, the scheme can extended to signature scheme for universal specified threshold verifiers and can achieve security in the random oracle model and on the difficulty of Computational Diffie-Hellman Problem.
