scope:

This Standard specializes ISO/IEC 11740-3 "Informational Technology - Security Techniques - Key Management - Part 3: Mechanisms using asymmetric techniques" for use by the financial services industry.

This Standard defines key establishment schemes that employ asymmetric cryptographic techniques. The arithmetic operations involved in the operation of the schemes take place in the algebraic structure of an elliptic curve over a finite field.

Both key agreement and key transport schemes are specified.

The schemes may be used by two parties to compute shared keying data that may then be used by symmetric schemes to provide cryptographic services, e.g., data confidentiality and data integrity.

Supporting mathematical definitions and examples are also provided.
