James Lee Massey ( born February 11, 1934 , Wausen, Ohio - June 16, 2013 ) is an American scientist who has made a significant contribution to information theory and cryptography. He was an Emeritus professor of digital technology at the Swiss Higher Technical School in Zurich . His most significant works are the application of the Alvin Burlekamp algorithm for finding the shortest shift register with linear feedback to linear codes ( Berlekamp-Massey algorithm ), the development of block encryption algorithms IDEA (together with Suejia Laye ) and SAFER , the Massey-Omura cryptosystem (together with ).

Biography
Massey was born on February 11, 1934 in Wausen, Ohio . He grew up in a large family. At the age of six, Massey was left without a father. Soon after, his mother got married and the whole family moved to Mendota , Illinois . After studying there until the age of 14, the Massey family moved to Ottawa . For the next 7 years, he and his brother attended a local parish school. Massey was very good at mathematics, but he was never interested in scientific experiments. He received his higher education at the University of Notre Dame . So in 1956, Massey received a bachelor of science degree in electrical engineering. After three years of military service, in 1959 Massey entered the Massachusetts Institute of Technology , where he focused on coding theory. In 1962, he received a Ph.D. In his second year of graduate school, Massey decided that he would like to go to the field related to information. There he met people like Fano and Shannon. Massey chose a convolutional code as the topic for his dissertation. After graduating, Massey decided to return to the University of Notre Dame , where he continued to study radio engineering until 1977. Here he got a job as a teacher at the Faculty of Electrical Engineering. Massey received the Thomas Madden Award for his significant contribution to the training of freshmen at the University of Notre Dame. He stayed at the university from 1962 to 1977. Massey was very active in the university. So he was the head of the SLC committee (Eng. Student Life Counsil). There, Massey conducted research in the field of coding and communication achievements. Together with Barleycamp, he developed the algorithm for finding the shortest shift register with linear feedback for the input binary sequence . From 1966 to 1967, Massey decided to take a vacation and go to the Massachusetts Institute of Technology . Here he taught a postgraduate course called algebraic coding. Massey also worked with his best friend Gallagher, whom he helped complete a book on information theory. From 1971 to 1972 Massey spent at the Danish Institute of Technology. There he taught courses. In 1977, Massey decided to leave the University of Notre Dame in connection with a divorce from his wife. At the same time, he was invited to Los Angeles and to the UCLA faculty at the Massachusetts Institute of Technology . Massey agrees. After a year at the Massachusetts Institute of Technology, he became interested in the dissertation of one of the Gallager doctoral students, which was called the collision resolution algorithm. In 1980, Massey returned to the Swiss Higher Technical School of Zurich. During this time, he worked in the field of security with cryptography and encryption secrecy and the study of random access communications. Massey, together with one of his best friends, Omura, made a couple of inventions and filed applications for their patents. In the future, one of them was called the Massey-Omur algorithm . Massey also developed the SAFER code. After some time, this cipher was finalized and adopted as the basis of the authentication protocol in Bluetooth . In 1982, Massey was asked to give fundamental lectures in the field of cryptography at a university in China. At this time, he and PhD student Lai Xuejia developed a new block cipher, which they patented as IDEA (International Data Encryption Algorythm). In 1998, Massey retires and moves to Copenhagen , where he lives there until his death.
He died of cancer on June 16, 2013 at his home in Copenhagen , Denmark .
