Applied cryptography is essential for security 电子商务需要运用密码技术解决安全问题。
Cool ideas in applied cryptography bruce schneier discusses plenty of cool things you can do with cryptography Bruce schneier讨论了许多您可以用密码学来做的很酷的事情。
In chapter 2 , the basic algorithms and protocol of applied cryptography are introduced here , including symmetric - key cryptography , public - key cryptography , hash functions and key management protocols 第二章介绍基本的应用密码学算法和密码协议,包括对称加密算法、非对称加密算法、散列函数、数字签名技术和密钥管理协议。
Public key infrastructure ( pki ) solves the problem effectively through certification , a process that binds a public key to a special entity . pki enables us to apply cryptography theories into security practice 如何将密码学的理论投入实际应用之中有效的解决安全问题,我们需要一种机制解决公钥与实体身份之间的绑定问题,这就是pki 。
The block cipher is one of the two aspects of the modern applied cryptography systems . it has some characteristics - the fast speed , the easy standardization , convenient implement by software and hardware , and so on . the block cipher always is the main parts of the data encryption , digital signature , authentication and key management in the security of information and network 分组密码是现代密码体制发展的两个方向之一,它具有速度快、易于标准化和便于软硬件实现等特点,通常是信息与网络安全中实现数据、数字签名、认证和密钥管理的核心体制,因此分组密码在计算通信和信息系统安全领域中具有广泛的应用。
This article brings forward an application of a new encryption algorithm and secret hash digital signature that aim at the insecure factors . at the base of these algorithms we can realize the secure credit card system , which can accelerate the development of credit card . in this paper we firstly discuss the general concepts of applied cryptography , and then introduce the mostly used modern encryption methods and technologies 本文首先介绍了应用密码学的基本概念,然后介绍了目前常用的加密技术,认真分析了对称密钥加密方法、公开密钥加密方法等加密技术的优缺点,提出了一种新型的分组加密方法? ?排列码加密解密算法以及基于该算法的保密散列数字签名算法,并将其应用于信用卡系统,从而在一定程度上降低了信用卡因遗失、被盗、假卡等因素造成的损失。
