'Hash then Sign' Discussions

["Furlong, Judith" <Judith.Furlong@dell.com>]

At yesterday’s KMIP TC meeting I mentioned I’d send out links to some of the ‘Hash then Sign’ discussions associated with the PQC algorithms that have been happening on the NIST PQC Forum and within the IETF.

 

NIST PQC Forum

• Integration of Post-Quantum Signatures
• Design rationale for keyed message digests in SPHNICS+, Dilithium, FALCON? [cross with IETF CFRG]
• Whether to hash-then-sign with Dilithium and Falcon? [cross with IETF CFRG]
• Parameter selection for the selected algorithms

 

IETF Crypto Forum Research Group (CFRG) has had several long email discussions on the topic

• Whether to hash-then-sign with Dilithium and Falcon? [cross with NIST PQC Forum and IETF LAMPS]
• Design rationale for keyed message digests in SPHNICS+, Dilithium, FALCON? [cross with NIST PQC Forum]

 

IETF (Limited Additional Mechanisms for PKIX and SMIME (LAMPS)

• Whether to hash-then-sign with Dilithium and Falcon? [cross with IETF CFRG]
• How do we plan to solve the hash-then-sign paradigm in Dilithium, Falcon and Sphincs+)
