Abstract
Described is a secure system for generic pattern matching. In operation, the system determines if a pattern p, as presented by a second party, is within a textual pattern T, as maintained by a first party. In making such a determination, the system uses a series of binary value matrices and corresponding pairs of encrypted permuted matrices. Challenge bits are then used to generate permutations and later verify correctness of the various encrypted permuted matrices. If it is determined that pattern p is within text T, the, for example, an access protocol is initiated.
