Patent

CA 2296967

A method and apparatus (100) for authenticating information transmitted to a receiver is presented. An information block is encoded (220) to form a raw codeword. A secret cover sequence S is then generated (122) using a hashing variable (124) and a secret key (126). The secret cover sequence is applied (128) through a reversible function to the raw codeword to form a covered codeword. The covered codeword is transmitted and received (130) at a receiver. At the receiver, a secret cover sequence R is generated (150) using a hashing variable (152) and a secret key (154). The secret cover sequence R is applied (156) through a reversible function to the raw codeword to form an uncovered codeword. The uncovered codeword is decoded (158), and if too many errors are reported, the data is discarded (160).
