Abstract
Confidential data such as license data is encrypted using the symmetric key encryption algorithm alone which requires smaller computation amount, and is readily realized by hardware elements, as compared with the public key encryption algorithm. A license-data transmitter (y) encrypts license data LIC using two keys Kscy and Kssx supplied from a license-data receiver (x). The license data is provided to the license-data receiver in the form of encrypted license data E(Kscy, E(Kssx, LIC)). This enables high-speed processing without deterioration in security even if data access such as recording/readout of data is repeated.
