Matthew John Barton "Matt" Robshaw is a cryptographer. Formerly a lecturer at Royal Holloway, University of London and a member of the cryptography research group at France Telecom's Orange Labs, he is now a Technical Fellow at Impinj. He coordinated the Symmetric Techniques Virtual Lab (STVL) for ECRYPT. Robshaw's notable work includes the cryptanalysis of a number of cryptographic primitives, including the extension of linear cryptanalysis to use multiple approximations, and the design of the block ciphers Crab and RC6.
