This document describes SPAKE2, which is a protocol for two parties
that share a password to derive a strong shared key without
disclosing the password. 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).
