Malcolm John Williamson (born November 2, 1950 – died September 15, 2015) was a very smart British mathematician. He was also a `cryptographer`, which means he worked with creating and breaking secret codes.
In 1974, Malcolm Williamson secretly developed a way for two people to share a secret key over an insecure network. This important method is now known as the Diffie–Hellman key exchange. At the time, he was working for GCHQ, a British intelligence agency. Because of this, his research was `classified`, meaning it was kept secret by the government.
Another scientist, Martin Hellman, independently discovered the same key exchange method around the same time. Hellman received public credit for the discovery. Williamson's amazing work remained a secret until the British government made it public in 1997.
Early Life and Education
Malcolm Williamson was born in Stockport, United Kingdom. He showed great talent in mathematics from a young age.
He attended Manchester Grammar School. In 1968, he won first prize in the British Mathematical Olympiad. He also earned a Silver prize at the 1967 International Mathematical Olympiad in Yugoslavia. The next year, in 1968, he won a Gold prize at the International Mathematical Olympiad in Moscow.
After high school, he studied mathematics at Trinity College, Cambridge. He graduated from Cambridge in 1971. After spending a year at Liverpool University, he joined GCHQ in 1972. He worked there until 1982.
Later Career and Contributions
From 1985 to 1989, Williamson worked at Nicolet Instruments in Madison, Wisconsin. There, he was the main person behind two patents for digital hearing aids.
After that, he moved to the IDA Center for Communications Research in La Jolla, California. He continued his important work there for the rest of his career.
Malcolm Williamson's contributions to inventing public-key cryptography are very important. He worked alongside Clifford Cocks and James Ellis. Their work has been recognized with major awards. In 2010, they received the IEEE Milestone Award #104. In 2021, Malcolm Williamson was also inducted into the Cryptologic Hall of Honor. These awards celebrate his lasting impact on the world of secret codes and secure communication.
