GoldKey Security Corporation has announced that is will support two-factor authentication for Cisco’s upcoming release of its AnyConnect Secure Mobility VPN Client.

GoldKey’s security tokens with Elliptic Curve Cryptography capabilities can be used with the VPN client’s encryption of IP traffic based on the Suite B set of encryption algorithms designated by the National Security Agency (NSA) for Department of Defense communications.

NSA Suite B cryptography bases its encryption on the Advanced Encryption Standard using 128-bit or 256-bit keys, digital signatures with the Elliptic Curve Digital Signature Algorithm using curves with 256-bit and 384-bit prime moduli, key exchange using the Elliptic Curve Diffie-Hellman method and hashing based on the Secure Has Algorithm-2.

NSA Suite B cryptography for IPsec is a published standard in RFC 4869.
