Elliptic Curve Algorithms for Cryptographic Message Syntax (CMS) Asymmetric Key Package Content Type

Elliptic Curve Algorithms for Cryptographic Message Syntax (CMS) Asymmetric Key Package Content Type IECA This document describes conventions for using Elliptic Curve cryptographic algorithms with SignedData and EnvelopedData to protect the AsymmetricKeyPackage content type. Specifically, it includes conventions necessary to implement Elliptic Curve Diffie-Hellman (ECDH) with EnvelopedData and Elliptic Curve Digital Signature Algorithm (ECDSA) with SignedData. This document extends RFC 5959. [STANDARDS-TRACK]
