Fahn Filename : draft-ietf-ipsec-ike-auth-ecdsa-01.txt Pages : 5 Date : 06-Nov-00 This document describes how the Elliptic Curve Digital Signature Algorithm (ECDSA) may be used as the authentication method within the Internet Key Exchange (IKE) protocol.
		ECDSA provides authentication and non-repudiation with benefits of computational efficiency, small signature sizes, and minimal bandwidth, compared to other available digital signature methods.
		This document adds ECDSA capability to IKE without introducing any changes to existing IKE operation.

		The sufficient conditions include (i) a uniformity property and collision-resistance for the underlying hash function, (ii) pseudo-randomness in the private key space for the ephemeral private key generator, (iii) generic treatment of the underlying group, and (iv) a further condition on how the ephemeral public keys are mapped into the private key space.

	Modifications of ECDSA
		We describe two variants of ECDSA one of which is secure, in the random oracle model, against existential forgery but suffers from the notion of duplicate signatures.
		The second variant is also secure against existential forgery but we argue that it is likely to possess only four natural duplicate signatures.
		Our variants of ECDSA are analogous to the variants of DSA as proposed by Brickell \it et al.
