Manuel Mogollon


Manuel Mogollon has been involved in the field of cryptography since 1981, principally in the areas of encryption algorithms, product development, and academia. At AT&T Datotek, he collaborated with Datotek’s Chief Cryptographer in the development of encryption algorithms based on linear feedback shift registers and public key for several encryptor units. Mr. Mogollon coauthor of the manuscript, Statistical Methods for Key Generator Evaluation, a paper written to provide the theoretical background for a series of randomness tests that were implemented in a crypto algorithm diagnostic tool software. Mr. Mogollon has traveled extensively to many countries around the world, demonstrating from the mathematical point of view, the level of security of the different encryption algorithms used in AT&T Datotek products. He has given crypto seminars in Chile, Colombia, Egypt, Mexico, Spain, and Saudi Arabia. Currently, Mr. Mogollon is a Nortel Senior Manager and Adjunct Professor in the Graduate School of Management, Information Assurance, at the University of Dallas, Center of Academic Excellence in Information Assurance Education, where he teaches Cryptography and Network Security.
