Federal Information Processing Standard 186-1 will now support ANSI X9.31, which allows
for the use of RSA-encrypted digital signatures.

Government agencies will be able to use RSA applications without petitioning for

“The approval of ANSI X9.31 is a significant breakthrough for government agencies,
many of which are already using RSA technology and have been anticipating its acceptance
as an official approved security standard,” said Miles Smid, acting chief of

The agencies can now take direct advantage of RSA technology to protect unclassified
information, he said.
