How to Enhance a Superscalar Processor to Provide Hard Real-Time Capable In-Order SMT
This paper describes how a superscalar in-order processor must be modified to support Simultaneous Multithreading (SMT) such that time-predictability is preserved for hard real-ti...

Representing hard lattices with O(n log n) bits
We present a variant of the Ajtai-Dwork public-key cryptosystem where the size of the public-key is only O(n log n) bits and the encrypted text/clear text ratio is also O(n log n)...
