Patent Searching and Data


Title:
INFORMATION PROCESSING DEVICE, METHOD, PROGRAM, AND INTEGRATED CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2010/041442
Kind Code:
A1
Abstract:
Provided is a high-speed data synchronizing process in which the number of key decodings is reduced when a plurality of key databases are used to synchronize the same data, because the keys of another key database, which was preset, are used to update the data managed in the other databases. Key management software (116) for managing a key database A (120) and a key database B (121), which have tree structures, determines whether or not synchronization is needed when the encryption of data from a high-level application is requested. The keys in the other key database, which was preset, are used, and the encrypted data are synchronized. Thus, repeated loads of the encrypted keys to an encryption unit (114) are eliminated, and data is encrypted at high speed.
