A new microSD card containing a secure element and cryptocontroller has been released by G&D. It supports ECC up to 521 bits (F_p, I assume, and not F_2m), AES-256 and SHA-512. The main functionality is strong authentication to allow secure phone calls.
Note: authentication is all well and good, but the security chain is only as strong as its weakest link.The main problem with open systems and mobile/ad hoc clients is key management, and I have yet to come across a practical, secure and dynamic solution in the Secure Voice market.
