Abstract
A method for generating a pattern matching machine for identifying matches of a plurality of symbol patterns in a sequence of input symbols, the method comprising: providing a state machine of states and directed transitions between states corresponding to the plurality of patterns; applying an Aho-Corasick approach to identify mappings between states in the event of a failure, of the state machine in a state and for an input symbol, to transition to a subsequent state based on the directed transitions of the state machine, characterized in that one of the symbol patterns includes a wildcard symbol, and mappings for one or more states representing pattern symbols including the wildcard symbol are based on an input symbol to be received, by the pattern matching machine in use, to constitute the wildcard.
