Practical Strong Security for Mobile Handheld Devices

چکیده
We present a method for constructing signature schemes for use with mobile handheld devices that mitigates the risk of an attacker forging signatures using key material garnered from a lost handheld. This scheme is forward-secure, meaning that signatures created before a breach are still valid, and server-assisted, meaning that a separate untrusted server must assist the device in signing, thereby protecting against offline dictionary attacks. We also present our experience with implementing these types of signature schemes for Java-enabled mobile devices, and the results of our experiments with this implementation.
