Abstract

Real random numbers produced by a physical process are important for many applications in cryptography. This report presents a mechanism for collecting random numbers based on physical noise sources in a standard hard disk drive. We apply statistical tests to show that high quality random numbers can be produced at a speed of up to 835,200 bits/s. As this process can be implemented on any Maxtor disk drive in a standard PC, no additional hardware is needed to obtain these numbers. A US-patent is pending.
