Dear Art,

May I give feedback on an old action item regarding the preference for ECDSA vs. DSA. I hope that T-Mobile's position statement is not too late.

T-Mobile favors ECDSA. DSA has no advantage regarding speed and memory consumption against the classic RSA. ECDSA improves the security level.

Please note that ECDSA supports prime field cases and binary field cases. Especially the binary field cases are covered by patents.

Due to the fact that different parameters for the elliptic curves can be used or are standardized, these parameters are relevant too. The NIST recommends fifteen elliptic curves (five prime curves and ten binary curves, see also http://en.wikipedia.org/wiki/Elliptic_curve_cryptography). The so-called Brainpool curves are preferred in Germany (see also http://www.ietf.org/internet-drafts/draft-lochter-pkix-brainpool-ecc-03.txt).

Best Regards,
