Abstract

We present a simple secure software smartcard that can be immunized against offline dictionary attack when the adversary captures the device. The proposed scheme also provides proactive security for the device’s private key, i.e., proactively updates to the remote server and device to eliminate any threat of offline dictionary attacks due to previously compromised devices.
