Q1) Identify the FIPS standard that provides the specification of the Digital Signature Standard.

Q2) NIST has published its recommendations on how need to generate or to verify digital signatures can determine whether or not a particular implementation is trustworthy. These recommendations include four specific "assurances" that are needed to have confidence in the authenticity of the process. Ten points will be awarded to the first student who can identify these four assurances and explain what they mean. Be sure to tell us where we can obtain a copy of this NIST recommendation.
