Key Establishment Using Integer-Factorization Schemes

Control changed

Before · SP 800-57 Part 1 Rev. 4

[SP800-56B] provides key-establishment schemes that use integer-factorization-based public- key algorithms (e.g., RSA). These schemes are provided in [SP 800-56B] for both key agreement and key transport, and, in some cases, key confirmation can also be provided. In these schemes, one party always owns and uses a key pair, and the other party may or may not use a key pair, depending on the scheme. Only static keys are used in the [SP800-56B] schemes; ephemeral keys are not used.
