| 摘 要： | 针对一种基于身份一次性公钥的构造方案给出2种攻击方法，指出其是可伪造的。基于超奇异椭圆曲线并利用一般椭圆曲线签名算法对基于身份的一次性公钥方案进行重新构造，新的构造方案能够抵抗伪造性攻击，是安全高效的。由于用户每次可以使用不同的公钥，方案可用于解决Internet通信中的匿名认证问题，实现用户隐私的有效保护。

| Abstract: | A dynamic evolution model of the internetware system based on component is proposed in order to meet the need that internetware system is able to evolve during the runtime. The model takes component as elementary unit and bases on software architecture to deploy and implement the evolution. It takes evolutionary algorithms of component adding, deleting and replacing into account, and introduces consistency checking mechanism to guarantee safety and reliability of the evolution. The model is easy to implement and has universal applicability, so that software systems is able to adapt to the evolution model without a great deal of modification. |
