Recommendation for Pair-Wise Key Establishment Using Integer Factorization Cryptography



Elaine B. Barker, Lidong Chen, Allen L. Roginsky, Richard Davis, Scott Simon


This Recommendation specifies key-establishment schemes using integer factorization cryptography (in particular, RSA). Both key-agreement and key transport schemes are specified for pairs of entities, and methods for key confirmation are included to provide assurance that both parties share the same keying material. In addition, the security properties associated with each scheme are provided.
