Title: The Innovative Contributions of Donald Preston Matthews, Jr.

Introduction

Donald Preston Matthews, Jr. is a notable inventor based in Longmont, CO (US). He has made significant contributions to the field of technology, holding a total of 10 patents. His work primarily focuses on enhancing security in computer systems and improving random number generation.

Latest Patents

One of his latest patents is the "Address-dependent key generator by XOR tree." This method provides security in a computer system by producing multiple sub-keys from key material and a respective address of a memory location. The process involves mixing these sub-keys using a binary tree of exclusive-or operations to generate an intermediate result. A scrambling operation is then performed on this result to create a key for producing a block of ciphertext. The method also includes writing this ciphertext to the memory location associated with the respective address.

Another significant patent is the "Active test and alteration of sample times for a ring based random number generator." This apparatus includes a test circuit that determines the randomness of bits sampled from a bit generator. If the sampled bits are found to be non-random, the sample frequency is adjusted accordingly. This innovation is crucial for ensuring the reliability of random number generation.
