Description / Abstract:

This part of ISO/IEC 18370 specifies blind digital signature mechanisms, together with mechanisms for three variants of blind digital signatures. The variants are blind digital signature mechanisms with partial disclosure, blind digital signature mechanisms with selective disclosure and traceable blind digital signature mechanisms. The security of all the mechanisms in this part of ISO/IEC 18370 is based on the discrete logarithm problem.

For each mechanism, this part of ISO/IEC 18370 specifies the following:

- the process for generating the keys of the entities involved in these mechanisms;

- the process for producing blind signatures;

- the process for verifying signatures.

This part of ISO/IEC 18370 specifies another process specific to blind signature mechanisms with selective disclosure, namely, the following:

- the presentation process.

Furthermore, this part of ISO/IEC 18370 specifies other processes specific to traceable blind signature mechanisms, namely, the following:

a) the process for tracing requestors;

b) the process for tracing signatures;

c) the requestor tracing evidence evaluation process (optional);

d) the signature tracing evidence evaluation process (optional).
