CAN/CSA-ISO/IEC 15946-3-04

Scope

International Standard ISO/IEC 15946 specifies public key cryptographic techniques based on elliptic curves. The standard is split into four parts and includes the establishment of keys for secret key systems and digital signature mechanisms.

This part of ISO/IEC 15946 specifies techniques for key establishment, which includes key agreement and key transport, that use elliptic curves. The scope of this standard is restricted to cryptographic techniques based on elliptic curves defined over finite fields of prime power order (including the special cases of prime order or characteristic two).

The representation of elements of the underlying finite field is outside the scope of this standard. This standard does not fully specify the implementation of the techniques it defines.

There may be different products that comply with this International Standard and yet are not compatible.
