Abstract (in Japanese) (See Japanese page) 
(in English) The pattern matching of the strings using hardware has the problem that increases circuit size when the number of patterns to be compared increases.
Then, we propose pattern matching techniques using dynamically reconfigurable hardware. The proposed circuit consists of fixed part that always maintains the comparison circuits for the leading strings of all comparison patterns and dynamically reconfigurable part that can contain the comparison circuits for the following strings according to the matching situation to the input data. When we assume
application to the malware detection and the objects of comparison are virus patterns of ClamAV, it became clear that the circuit size of dynamically reconfigurable part can be reduced without losing ability for detection. The proposed circuit with 2-character comparison circuits was estimated at 3.1% of size of the circuit that contains AND
gates and FFs for all compared patterns, and 7.7% with 5-character comparison circuits.
