Otherwise, license from Certicom or RSA Data Securities. The best I can tell, if the patents are valid, then RSA Data Securities is infringing. License from RSA Data Securities and let them slug it out with Certicom. > (Someone pointed out to me recently that the redhat shipped openSSL is > devoid of ECC which is kind of a nuisance!) RedHat is acorporation with money. If you are not a corporation or don't have money, then don't worry about it. You can't get water form a rock. > Suite B pushed use of EC you would think would increase the interest in > having clarity on the EC patent situation.. Suite B uses ECC and has a minimum security level of 128 bits. You can still achieve the security level with DH-3072 (and subgroups of 256 or greater), RSA-3072, SHA-256, etc. Jeff _______________________________________________ cryptography mailing list [email protected] http://lists.randombit.net/mailman/listinfo/cryptography
