It seems that it is in fact an NXP PN544. Anyway having a secure element integrated in the Nexus S would be great news, even if it take some time to be able to use it. But knowing that the chip can support a secure element does not mean that there is one. > > Any ideas on how to use this security chip?

I was not able to find anything in the current AOSP, but I think that a lot of work would be needed to have this. First you need the integration of pcsclite, similar to what seek-for-android did. But after this someone need to write a PKCS#11 provider implementation, similar to the SunPKCS11 provider. I was not able to find one, either in Apache Harmony or BouncyCastle, so that probably something that had to be written from scratch. After this, and assuming that the Nexus S really contains a secure element, any Android app will be able to store/generate and use RSA/ECC keys in a secure way. - -- Marc Petit-Huguenin Personal email: [email protected] Professional email: [email protected] Blog: http://blog.marc.petit-huguenin.org -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iEYEARECAAYFAk1yYcsACgkQ9RoMZyVa61fSMACfTmbS1RpO96mVm4D2QdpP5OBh HUAAn2HuxgsciCfo89O01bJSIp0IsOgb =nvN4 -----END PGP SIGNATURE----- -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
