A digital signature for a document is usually constructed by cryptographically hashing the document , and then encrypting the hash using a private key 用于文件的数位签章经常由对文件的加密杂凑构成,然后用专用密钥加密杂凑。
The vulnerability could , under certain circumstances , allow a malicious user to obtain cryptographically protected logon credentials from another user when requesting an office document from a web server 在特定的条件下,该漏洞使恶意用户可以在从web服务器上请求office文档时获取其他用户有加密保护的登录凭据。
Because your custom permission s assembly and any assemblies it references will be fully trusted by the security system , it is important that those files be signed with a cryptographically strong name 因为安全系统将完全信任您的自定义权限的程序集(以及它引用的任何程序集) ,所以对这些文件用加密型强名称进行签名很重要。
In traditional block cipher , the s - box is the only one nonlinear core component and it determines the strength of these cryptosystems . therefore , the construction of cryptographically strong s - boxes is of much 在传统分组密码学中, s盒是唯一一个非线性运算部件,它的性能直接影响到整个密码系统的强度,它的设计一直是密码设计与密码分析的研究重点。
In this paper , many technology scheme on xml signature , xml encryption and xml access control are studied . we propose a new signcryption schema based on the research of cryptography theory and present the cryptographically access control for xml and the implement of xml security communication 本文研究了基于xml的加密、数字签名和xml的访问控制等安全技术方案;在密码学理论和web安全技术研究的基础上提出了一种基于身份的签密方案、加密xml的访问控制方案并实现了一种基于xml的安全通信。
In tcp / ip protocol suite , the ipsec protocol provide interoperable , high quality , cryptographically - based security for ipv4 and ipv6 . the set of security services offered includes access control , connectionless integrity , data origin authentication , protection against replays ( a form of partial sequence integrity ) , confidentiality ( encryption ) , and limited traffic flow confidentiality 在tcp ip协议族中, ipsec ( internetprotocolsecurity )协议提供的安全服务保证数据在网络传输过程中的机密性、完整性和抗重放保护,以及对网络通信中的通信流分析攻击提供有限的保护, ipsec协议还提供对网络的访问控制能力。
Furthermore , some novel cryptography technology such as chaotic cryptography , quota cryptography are paid much attention by researchers beside conventional cryptography . in this paper , we propose a new chaotic searching simulated annealing method based on chaotic cryptography and intelligent computing to obtain cryptographically strong s - boxes 在传统的利用代数方法设计密码学的基础上,一些新兴的密码学理论,如混沌密码学、量子密码学等等也引起了愈来愈多的学者的青睐。
