This method is compatible with any group, is computationally efficient, and has a security proof. This document predated the Crypto Forum Research Group (CFRG) password-authenticated key exchange (PAKE) competition, and it was not selected; however, given existing use of variants in Kerberos and other applications, it was felt that publication was beneficial. Applications that need a symmetric PAKE, but are unable to hash onto an elliptic curve at execution time, can use SPAKE2. This document is a product of the Crypto Forum Research Group in the Internet Research Task Force (IRTF).", "pub_date": "September 2023", "keywords": [], "obsoletes": [], "obsoleted_by": [], "updates": [], "updated_by": [], "see_also": [], "doi": "10.17487/RFC9382", "errata_url": null }
