Another mistake is for developers to try to hand roll their own protocols using common cryptographic primitives , not fully understanding that cryptographic protocols are generally more complex than expected and easy to get wrong 另一个错误是开发人员尝试使用公用的密码原语来施行他们自己的协议,却没有完全理解密码协议通常比想的更复杂,并且容易出错。
With the ceaselessly development of network , the security of network information becomes more and more important ; as the foundation of the security of network information , the security of cryptographic protocols becomes the key of this problem 随着网络的不断发展,网络信息安全变得日益重要,安全协议作为网络信息安全的基础,它的安全性变成了一个关键的问题。
With the popularization of network and flourishing of internet applications , security protocols are becoming more and more important , furthermore , ensuring the security of cryptographic protocols has become an important research task 随着网络的普及以及电子商务和电子政务蓬勃兴起,安全协议变得越来越重要,确保安全协议的安全性已经成为一项重要的研究课题。
The model has some properties as follows : can give accurate formal specifications for cryptographic protocols ; has provable semantics which is reasonable and sound ; can define the security properties precisely and reasonably ; is easy to realize automatic deductions 该模型具有以下特点:能够对密码协议进行精确的形式化描述;具有合理可靠的可证明语义;对密码协议安全性的定义精确合理;便于实现自动化推理。
Because of the importance of non - repudiation to electronic commerce activities and the fact that non - repudiation protocol is relatively few , this paper adopts the modern cryptographic algorithms and techniques and designs a mutually undeniable cryptographic protocol 介于不可否认协议对电子商务活动开展的重要性以及不可否认协议相对较少这一事实,利用现有的密码算法与密码技术,提出一种改进的双方不可否认密码协议方案。
A security protocol (cryptographic protocol or encryption protocol) is an abstract or concrete protocol that performs a security-related function and applies cryptographic methods.
