Michael George Luby is a mathematician and computer scientist, VP Technology at Qualcomm and former co-founder and Chief Technology Officer of Digital Fountain. In coding theory he is known for leading the invention of the Tornado codes and the LT codes. In cryptography he is known for his contributions showing that any one-way function can be used as the basis for private cryptography, and for his analysis, in collaboration with Charles Rackoff, of the Feistel cipher construction. His distributed algorithm to find a maximal independent set in a computer network has also been very influential. He has also contributed to average-case complexity. Luby received his B.Sc. in mathematics from MIT in 1975. In 1983 he was awarded a Ph.D. in computer science from UC Berkeley.〔 *〕 In 1996-1997, while at the International Computer Science Institute (ICSI), he led the team that invented Tornado codes. These were the first LDPC codes based on an irregular degree design that has proved crucial to all later good LDPC code designs, which provably achieve channel capacity for the erasure channel, and which have linear time encoding and decoding algorithms. In 1998 Luby left ICSI to found the Digital Fountain company, and shortly thereafter in 1998 he invented the LT codes, the first practical fountain codes. Qualcomm acquired Digital Fountain in 2009.〔(StreamingMedia.com blog )〕 ==Awards received== * 2002 IEEE Information Theory Society Information Theory Paper Award for leading the design and analysis of the first irregular LDPC error-correcting codes〔(【引用サイトリンク】publisher=IEEE Information Theory Society )〕 * 2003 SIAM Outstanding Paper Prize for the seminal paper showing how to construct a cryptographically unbreakable pseudo-random generator from any one-way function * 2007 IEEE Eric E.
