Announcing Draft Federal Information Processing Standard (FIPS) 186-3, Digital Signature Standard (DSS), and Request for Comments
March 12, 2006

"This notice announces Draft Federal Information Processing Standard 186-3, Digital Signature Standard, for public review and comment. The draft standard, designated “Draft FIPS 186-3,” is proposed to revise and supersede FIPS 186-2.

FIPS 186, first published in 1994, specifies a digital signature algorithm (DSA) to generate and verify digital signatures. Later revisions (FIPS 186-1 and FIPS 186-2, adopted in 1998 and 1999, respectively) adopt two additional algorithms specified in American National Standards (ANS) X9.31 (Digital Signatures Using Reversible Public Key Cryptography for the Financial Services Industry (rDSA)), and X9.62 (The Elliptic Curve Digital Signature Algorithm (ECDSA)).

The original DSA algorithm, as specified in FIPS 186, 186-1 and 186-2, allows key sizes of 512 to 1024 bits. With advances in technology, it is prudent to consider larger key sizes. Draft FIPS 186-3 allows the use of 1024, 2048 and 3072-bit keys. Other requirements have also been added concerning the use of ANS X9.31 and ANS X9.62. In addition, the use of the RSA algorithm as specified in Public Key Cryptography Standard (PKCS) #1 (RSA Cryptography Standard) is allowed.

Prior to the submission of this proposed standard to the Secretary of Commerce for review and approval, it is essential that consideration is given to the needs and views of the public, users, the information technology industry, and Federal, State and local government organizations. The purpose of this notice is to solicit such views."
