标准范围

数字签名机制有两种:当验证过程需要电文作为输入的一部分时，该机制被称为“带附录的签名机制”。在附录的计算中使用了散列函数。当验证过程揭示全部或部分消息时，该机制被称为“给予消息恢复的签名机制”。散列函数也用于这些签名的生成和验证。ISO/IEC 14888规定了带有附录的数字签名。ISO/IEC 14888-1:20 08规定了数字签名的一般原则和要求，并附有附录。ISO/IEC 14888-2处理基于整数分解的数字签名，ISO/IEC 14888-3处理基于离散对数的数字签名。ISO/IEC 9796中规定了提供消息恢复的签名机制。散列函数在ISO/IEC 10118中规定。

There are two types of digital signature mechanism:

• When the verification process needs the message as part of the input, the mechanism is called "signature mechanism with appendix". A hash-function is in used in the calculation of the appendix.


• When the verification process reveals all or part of the message, the mechanism is called a "signature mechanism giving message recovery". A hash-function is also used in the generation and verification of these signatures.

ISO/IEC 14888 specifies digital signatures with appendix. ISO/IEC 14888-1:2008 specifies general principles and requirements for digital signatures with appendix. ISO/IEC 14888-2 addresses digital signatures based on integer factoring, and ISO/IEC 14888-3 addresses digital signatures based on discrete logarithm.

Signature mechanisms giving message recovery are specified in ISO/IEC 9796. Hash-functions are specified in ISO/IEC 10118.
