Title:

INFORMATION PROCESSING DEVICE AND INFORMATION PROCESSING METHOD

Document Type and Number:

WIPO Patent Application WO/2012/160760

Kind Code:

A1

Abstract:

An information processing device which processes data to be secured comprises: a first storage unit (301); a second storage unit (302); and a cache control unit (303) which caches stored data on the first storage unit (301) in the second storage unit (302). The cache control unit (303) locks a cache region in the second storage unit (302) wherein stored data is cached in the second storage unit (302) such that cached data which is obtained from the cache region is not written back to the first storage unit (301). After the cache region in the second storage unit (302) is locked, then data to be secured, which is different from the stored data, is written to the cache region in the second storage unit (302).
