1 July 2016

We present a lightweight PUF-based authentication approach that is practical in settings where a server authenticates a device, and for use cases where the number of authentications is limited over a device's lifetime. Expand

IEEE 23rd International Conference on Application…
9 July 2012

This paper describes the systematic design methods of an embedded co-processor for a post quantum secure McEliece cryptosystem, which is 10 times faster and 3.8 times smaller than the existing design. Expand
