摘要： It is desired to share one circuit by an encryption unit 200 and a decryption unit 500. A normal data transformation unit (FL) 251 and an inverse data transformation unit (FL -1 ) 273 are located at point symmetry on a non-linear data transformation unit 220, and a normal data transformation unit (FL) 253 and an inverse data transformation unit (FL -1 ) 271 are located at point symmetry on the non-linear data transformation unit 220. Therefore, the encryption unit 200 and the decryption unit 500 can be configured using the same circuits.

摘要： A random number sequence is previously generated by the function f8 for data confidentiality processing, which generates a random number sequence, and stored in a random number sequence memory (buffer). When data (message) is input, the random number sequence stored in the random number sequence memory is obtained, and the data (message) is encrypted by an XOR circuit to generate ciphertext data. In case of decrypting data, a random number sequence is also previously generated by the function f8 for data confidentiality processing and stored in the random number sequence memory (buffer). When the ciphertext data is input, by the XOR circuit, the random number sequence stored in the random number sequence memory is read and the ciphertext data is decrypted into the data (message).

摘要： Portable terminal MS downloads coupon data and public key KEYP2 of IP server 20 from IP server 20. Service terminal T obtains from IP server 20, a server certificate to which a digital signature is applied by secret key KEYS2. One to one local communication by infrared radiation is performed between portable terminal MS and service terminal T. At this point, portable terminal MS decrypts a server certificate by utilizing public key KEYP2 of IP server 20. Then, portable terminal MS communicates specified data after authenticating the identity of service terminal T.

摘要： Data areas AR1 and AR2, lead-in areas LIN1 and LIN2, and lead-out areas LOUT1 and LOUT2 are provided on a disc. For example, in case of encrypting and recording data into the data area AR2, copyright management information R2 and key information K2 are recorded into the lead-out area LOUT2. Only information in a Q channel of a subcode is recorded in the lead-out area and this area is filled with dummy data. A position of the lead-out is obtained from TOC information. The fact that a light spot has entered the lead-out area can be judged from the information in the Q channel. The copyright management information and key information are recorded by using the lead-out area. The lead-out area is not rewritten or accessed by an ordinary CD player, so that the copyright management information and the key information can be safely held.

摘要： A system for providing visual display security on a general-purpose computer, the general-purpose computer capable of running an operating system and an application, the operating program system and application program presenting a user interface in the form of display windows, includes a display window having a default display characteristic and a computer security program operating on the general purpose computer. The computer security program altering the default display characteristic to a modified display characteristic, the modified display characteristic rendering the display window unreadable to a human eye. The system also includes an optical filter matched to the modified display characteristic so that the display window becomes readable when viewed through the optical filter.
