- George_B._Purdy abstract "George Barry Purdy is a mathematician and computer scientist who specializes in combinatorial geometry and number theory. He is the namesake of the Purdy polynomial, used in operating systems (e.g., OpenVMS) to hash user passwords. OpenVMS uses a 64-bit version, based on a 64-bit prime, that is starting to be considered insecure, but there is no theoretical limit to the size of the prime used, and it is rumored that there are classified military versions that are extremely secure. The notorious hacker Kevin Mitnick mentions the Purdy polynomial in his autobiography and says that it caused him to be found out. Purdy received his Ph.D. from the University of Illinois at Urbana–Champaign in 1972, under the supervision of Paul T. Bateman. He was on the faculty in the mathematics department at Texas A&M University for 11 years, and has been a professor of computer science at the University of Cincinnati for 28 years.He coauthored a number of papers with Paul Erdős, who claimed him as a student, and is the "P" in G.W. Peck, a pseudonym for a group of six mathematicians that includes Purdy. He is a founding member of the Institute of Combinatorics and its Applications.".
