Abstract

It is a challenge to develop nonlinear Pseudo random number generators (PRNGs) with high throughput rates and good unpredictability. Recently, the great need offered by high-speed wireless communications in hospital, including uploading of X-ray scan, Endoscopy, CT, and MRI image of patients has stimulated growing interest in nonlinear PRNGs for security-related applications. We propose a hardware-efficient, high-throughput, and hardly-predictable PRNG by transforming from software to hardware implementation. In this proposal, we may extend the nonlinear PRNGs on the following areas: 1. Reduce the hardware complexity via estimating truncation error in digital chaos circuit. 2. Extend the concept of mixing, such as shuffling, to enhance the throughput rate and minimize the hardware costs. 3. Build a merit to evaluate the unpredictability. In conclusion, the proposed fast and high unpredictability PRNGs can be integrated in High-speed wireless system for satisfying security requirement.
