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. The production of key pairs requires random bits and prime numbers.
The production of signatures often requires random bits. Techniques for producing random bits and prime numbers are outside the scope of this part of ISO/IEC 14888. For further information, see ISO/IEC 18031 and ISO/IEC 18032.
Various means are available to obtain a reliable copy of the public verification key, e.g., a public key certificate. Techniques for managing keys and certificates are outside the scope of this part of ISO/IEC 14888. For further information, see ISO/IEC 9594-8, ISO/IEC 11770 and ISO/IEC 15945.
