双语例句

• In forward-secure signature scheme, the operation is divided into time periods, with a different secret key for each time period. Each secret key is used to sign messages only during a particular time-period, while the public key for verifying signature remains unchanged.
  在前向安全数字签名中，签名的有效时间被分成若干个周期，在每个周期内使用不同的私钥产生签名，而验证签名的公钥在整个有效时间内保持不变。
• This paper proposed an efficient ID-based signature scheme without trusted party against the problem of key escrow of ID-based signature system.
  针对现有的基于身份签名系统的密钥托管问题，提出了一种高效的基于身份的无可信中心签名方案。
• Combing signature technology and bilinear maps technology, the problem of completely trusting of private key generator is solved. Not only the fault, user denies signatures, is preventing and the disfigurement, private key generator forges signature, is eliminated.
  结合签名技术，双线性映射技术，解决了密钥生成中心完全可信的问题，既防止用户否认签名，又避免了密钥生成中心伪造签名。
• If the proxy signer wans to use the same proxy key to signature different messages, his private key will be cracked.
  如果代理人两次用同一代理密钥签名，他的私钥就会被破译。
• In this protocol, the evidence problem based on reliable client is pointed out. Without public key signature algorithm, the evidence problem is solved by symmetric cipher and hash function.
  该协议提出了基于客户端可信的证据保留问题，并在不使用公钥数字签名算法的前提下，利用哈希函数与对称密码算法解决了证据保留问题。

  普通的代理签名算法有一个严重的缺陷：一旦签名密钥泄露，以前用该密钥签名的所有文档都失效。
• The other is modifying public key signature main mode to protect the initiator's identity.
  对公钥签名主模式进行改进，以保护发起者的身份信息。
• On the basis of a NP ─ completeness problem ( matrix cover problem), a new type of public key signature scheme is presented. Its velocity is quicker and its realization is easier. and discusses its safety character.
