利用ZCPA模型对四种转子故障进行了特征提取试验验证，结果表明，该模型只使用少量特征数据(如16个)即可有效表征不同故障，同时，对同一类型故障的特征提取结果具有很好的稳定性和一致性，具有一定的工程应用前景。

In this paper,a forward-secure threshold signature scheme based on the Asmuth－Bloom threshold scheme is proposed.Its security is based on the difficulty of solving discrete logarithm in finite field and quadratic residue on some special conditions.

基于Asmuth－Bloom门限方案，设计了一种新的前向安全的门限签名方案，其安全性基于有限域上求解离散对数的困难性和在特定条件下求解二次剩余问题的困难性。

In order to improve the security, a signature scheme based on two hard problem assumptions is proposed. The security of the scheme is based on the difficulties of simultaneously solving the elliptic curve and quadratic residue. A attacker can't forge the signature of messages even if a attacker can solve theelliptic curve discrete logarithm problems or quadratic residue problem in the scheme.

为了提高签名的安全性，本文对Wang等人提出的签名方案进行改进，提出了一个基于椭圆曲线离散对数问题和二次剩余问题的数字签名方案，并对该方案的安全性进行分析，指出在椭圆曲线离散对数问题或二次剩余问题可解的情况下，攻击者也无法伪造消息的签名。
