The results show that the KPW scheme is not a nominative signature scheme since the nominator not only can verify and prove the validity of given signatures but also can convert given signatures into universally verifiable signatures, and that the PL scheme is only a self-authentication signature scheme since anyone can verify the validity of given signatures.

摘要该文分别对一个指名签名方案和一个指名代理签名方案进行分析，结果表明：在KPW方案中签名人不仅能验证而且也能向第三方证明签名的有效性，甚至能将签名转化为通常的自认证签名，因此不是指名签名方案；在PL方案中任何人都可验证签名的有效性，它只是一个自认证签名方案。

Conceptually, we present the principle of optimality for defuzzification and the optimal defuzzification mapping; methodologically, we convert the problem of finding the optimal defuzzification mapping into the one of finding the optimal parameters, suggesting a specific method for its realization—POD method; operationally, we advance that the learning of the parameters for defuzzification can be realized by the learning process using extended Kalman filter.

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.
