ISO/IEC 14888-2:2008

Digital signatures with appendix -- Part 2: Integer factorization based mechanisms

SCOPE

This part of ISO/IEC 14888 specifies digital signatures with appendix whose security is based on the difficulty of factoring the modulus in use. For each signature scheme, it specifies:
a) the relationships and constraints between all the data elements required for signing and verifying;
b) a signature mechanism, i.e., how to produce a signature of a message with the data elements required for signing;
c) a verification mechanism, i.e., how to verify a signature of a message with the data elements required for verifying.

    This standard specifies digital signature techniques based on integer factorisation problem. They provide authenticity, integrity and non-repudiation. One of the main uses of these techniques are in Public Key Infrastructures. This standard has been confirmed in 2016 and seems mature and stable. Although, it just went through the review process at ISO. Several National Bodies voted to review it, but the majority voted to confirm it. The final decision will be taken in October 2019 at the next meeting. In the case of the advent of general-purpose large-scale quantum computers (which is yet far from happening), this standard will be shaken and will have to be revised.
