Nokia 6131/6212 - Crypto Capabilities

It looks like the secure chip in the Nokia NFC phones does not support Elliptic Curve Cryptography - RSA works fine though. I've tried to create ECC keypairs using NIST curve specifications SECP160K1 and SECT163K1 but the response is 0x6F03 (no such algorithm). However the latter curve does work (signature generation and verification OK) on my single and dual interface smart cards (JCOP20/JCOP30).

In my previous post I saw that the COS for the Nokia 6131 NFC is G&D SmartCafe Expert 3.1 In G&D's sparse public documentation and SmartCafe Expert 3.1 flyer only RSA is mentioned so I conclude ECC is definitely not supported. As an interesting side note, the flyer says the COS is JavaCard 2.2.1 compliant - which confirms a conclusion in an earlier post.


Since there are so few other mobiles with NFC I guess we'll have to wait for microSD cards with embedded NFC and secure elements which support ECC.
