签名者

In the Harn digital signature scheme,the signatory need not compute any inverses and the person who verifies the key only need compute two modular exponents, so the computation work is less in comparison with other schemes based on discrete logarithm.

Harn数字签名方案中，签名者不需计算任何逆，验证者只需计算 2个模指数，因此相对于其它基于离散对数数字签名方案计算量大大减少。

The security analysis of the proposed scheme shows that it satisfies non-transferability, unforgeability, privacy of signer's identity and has low computational cost.

分析表明，新方案满足不可转发性、不可伪造性以及签名者身份保密的性质，并且具有较高的效率。

A threshold signature scheme distributes the signing abilities to a group of signers, and avoids the system unsecurity.

门限签名方案将密钥进行分享，限制了由单个签名者所组成的系统的不安全性。

The Chih-Yin Lin was partially improved on to be more propitious for controlling the signature flow, inserting the signer's opinions and programming the algorithms on the web.

对多重签名方案做了部分改进，使之更利于流程的控制、签名者意见的加入和在网络上的算法实现。

If the signer repudiates the signature dispute in the case of a later dispute, the exciting schemes need to reveal the recovered message to the third party, cooperate with the signer, or to perform a zero-knowledge protocol.

在已有的方案中，解决事后的争议时，需要签名者的合作、需要向第三方提供恢复的消息、需要与第三方执行交互的零知识证明，所以效果并不是很好。

Designated multi-verifiers signature schemes allows signer to designate the signature to a set of verifiers,in such a way that only designated verifiers can verify the efficiency of the signature,but is unable to convince anyone else of this fact.

指定多个验证者签名方案允许签名者指定多个签名的验证者，只有这些指定的验证者们可以验证签名的有效性，但他们却不能向其他人证明这一事实。

In the scheme, the signature can be verified independently by each of the n designated verifiers designated by the signer and no one else than the designated person can be convinced by this signature even if one of the designated verifiers reveals the secret value.

在此方案中，只有签名者指定的n个验证者可以各自独立地验证签名，并且即使其中某个指定验证者将自己的秘密值泄漏，其他的任何人也无法验证签名的真伪。

Boneh's one round multi-party key agreement protocol and Chameleon hash, a multi-designated verifiers signature scheme was proposed. The security analysis of the proposed scheme shows that it satisfies non-transferability, unforgeability, privacy of signer's identity and has low computational cost.

Boneh的多方密钥协商方案以及Chameleon哈希，提出了一个新的指定多个验证者的签名方案，并证明了新方案满足不可转发性、不可伪造性以及签名者身份保密的性质，并且具有较高的效率

In the scheme,the signer may generate a ciphertext of signsture for a message by using the own personal key,and transmit the ciphertext to a specified group of verifiers which adoptes threshold scheme.Any tout of nverifiers in the group can share the authoring for message recovery.

在该方案中，签名者利用其个人密钥可以生成信息签名的密文并送给特定的验证组，采用门陷方案的该验证组n位中的t位能共享对信息进行恢复的权力。

By using a more secure signing algorithm to sign the signers' intentions, the problem was solved.

通过使用更安全的算法对签名者的意向进行签名避免了这一弱点。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
