This probably refers to the ANSI X9 financial standards
committee, whose X9F Subcommittee on Data and Information
Security devises cryptographic standards in cooperation with
the global financial services community and various standards
groups. See general info at the X9 home page:
http://www.x9.org/
Most of the X9F subcommittee portion of the site is restricted to
members. However, Rich Ankey <[EMAIL PROTECTED]>, who heads,
or headed, the subcommittee is informative about its workings. There
sub-subcommittees on "cryptographic tools," "protocols,"
"applications," and "certificates."
See one of Rick's papers "Introduction to Cryptographic Standards,"
at NISSC 97:
