NIST requests comments on Federal Information Processing Standard (FIPS) 186-4, Digital Signature Standard, which has been in effect since July 2013. FIPS 186-4 specifies three techniques—RSA, DSA, and ECDSA--for the generation and verification of digital signatures, along with a set of elliptic curves recommended for government use.
NIST primarily seeks comments on the recommended elliptic curves specified in Appendix D of the FIPS, but comments on other areas of the FIPS will also be considered.
