标准范围

ISO/IEC 15946-4:20 04专门解决了基于椭圆曲线的消息恢复的数字签名。ISO/IEC 15946-4:20 04的范围限于基于在素数幂阶的有限域上定义的椭圆曲线的密码技术（包括素数阶和特征二的特殊情况）。基础有限域的元素的表示（即使用哪个基）超出了ISO/IEC 15946-4:20 04的范围。ISO/IEC 15946-4:20 04规定:数字签名提供具有每种类型冗余的消息恢复:自然冗余、附加冗余或两者兼而有之。数字签名的一般模型提供部分或全部消息恢复，旨在减少存储和传输开销。结合一般模型，给出了基于椭圆曲线的数字签名消息恢复的五种实现机制。在ISO/IEC 15946-1中描述了实现这些机制所需的数学背景和一般技术。

ISO/IEC 15946-4:2004 specifically addresses the digital signatures giving message recovery based on elliptic curves. The scope of ISO/IEC 15946-4:2004 is restricted to cryptographic techniques based on elliptic curves defined over finite fields of prime power order (including the special cases of prime order and characteristic two). The representation of elements of the underlying finite fields (i.e. which basis is used) is outside the scope of ISO/IEC 15946-4:2004.ISO/IEC 15946-4:2004 specifies:

• the digital signatures giving message recovery with each type of redundancy: natural redundancy, added redundancy, or both.
• the general model for digital signatures giving partial or total message recovery aiming at reducing storage and transmission overhead.

Together with the general model, it provides five mechanisms to realize the digital signatures giving message recovery based on elliptic curves.The mathematical background and general techniques necessary for implementing the mechanisms are described in ISO/IEC 15946-1.
