| 1. | Before we cover that , let s talk about nonrepudiation
在讨论这个问题之前，我们先说一说抗抵赖。 |
| 2. | By the same token , nonrepudiation refers to the ability of a system to counter repudiation threats
同理，无否认是指系统应对否认威胁的能力。 |
| 3. | As levy observes , “ this nonrepudiation feature is the electronic equivalent of a notary public seal
正如列维认为： “这种不可否认性特征是公证人印章的电子等价物。 ” |
| 4. | Nonrepudiation provides evidence that a particular action occurred and can be traced to a specific entity user or business
抗抵赖性提供了发生过某个动作的证据，并且可以跟踪到特定的实体（用户或者公司） 。 |
| 5. | The purposes of the certificate are considered valid if the certificate has no key usage or if the key usage supports digital signature or nonrepudiation
如果证书没有密钥用法或如果密钥用法支持数字签名或认可，则认为该证书的用途有效。 |
| 6. | Besides role - based access control , it provides for identity authentication , encryption to keep information confidential , data integrity , and nonrepudiation
Ncds方案在局域网内实现了企业级认证中心ca ( certificateauthority )以承担pki中核心的证书管理工作。 |
| 7. | Nonrepudiation validation and authorization of soap message . at last , design a component of message security , which can realize soap encryption and soap signature
在消息安全解决方案的基础上，又设计了消息安全组件，该组件能实现soap消息加密及soap消息签名。 |
| 8. | In addition , we give the nonrepudiation proof using kailar logic . although the proof based on logic is only a prerequisite to security , it can enhance users " confidence considerably
接着使用kailar逻辑证明了其可追究性，虽然基于逻辑的证明只是满足协议安全目标的必要条件，但该证明的给出可以显著增强使用mb协议的信心。 |
| 9. | 3 . base on the theory of embedded database and the requirement of security services , an embedded database is analyzed and realized , which can provide authentication services , access control services and nonrepudiation services
基于嵌入式数据库和eiscp对安全服务的需求，设计并实现了包含用户信息表和访问日志表的数据库，提供身份认证、访问控制和抗抵赖服务。 |
| 10. | The paper designs a data encryption system for network communication , which combines the private - key algorithm 3des with the public - key algorithm rsa to encrypt data and signs on files with public - key algorithm rsa and one - way hash function md5 . the system can actualize encryption of data , digital signature and identification efficiently and ensure privacy , authenticity , integrity and nonrepudiation of data
在此基础上，本文设计了网络通信数据加密系统，该系统将对称加密算法3des与非对称加密算法rsa相结合对数据加密，用公钥算法rsa和单向散列函数md5实现对文件的数字签名，有效地实现了网络通信系统中的信息加密、数字签名、身份认证等功能，保证了发送方所发送信息的秘密性、鉴别性、完整性及不可否认性。 |
