摘要： A first device generates first encrypted data from a second public key corresponding to second ID regarding a second device and a first random number and transmits first ID regarding the first device, second ID, and first encrypted data. The second device generates second encrypted data from a first public key corresponding to the first ID and a second random number, generates second verification data by generating a second shared-key candidate from the second random number, the first encrypted data, and a second private key, and transmits the second encrypted data and second verification data. The first device generates first verification data by generating a first shared-key candidate from the first random number, the second encrypted data, and a first private key and transmits the first verification data. The first and second devices examine the second and first verification data by using the first and second shared-key candidates, respectively.

摘要： An encryption apparatus using a common cipher key, which is resistant to differential power analysis. A first route selection device (102-1, 203, 911) rearranges a plurality of extended key mask values (c 0 -c 3 ) at random according to the value of a random number generated by a random number generation device (101, 901) . An extended key operation device (103, 201, 202, 909, 910) generates an exclusive logical OR of a plurality of the rearranged extended key mask values, a data string representing extended key (K) and an input data string (M) . The second route selection device (102-2, 204, 912) rearranges the data string of the exclusive logical OR oppositely to the first route selection device according to the value of the random number. A non-linear conversion device (104, S' 0 -S' 3 , 913) applies non-linear conversion to the rearranged data string and outputs a data string masked by a plurality of non-linear conversion mask values (d 0 -d 3 ). The third route selection device (102-3, 205, 914) rearranges the masked data string the same way as the first route selection device according to the value of the random number. In this way power consumption in the encryption apparatus is randomized.

摘要： Disclosed is a digital document management program capable of achieving a third-party certification of document information with reduced amount of meta data.
At the registration time of new document information, the digital document management program manages a digital signature created in association with document information. At the correction time of the document information, the program acquires partial identification information related to a corrected part of the document information before correction, creates a digital signature to be appended to the corrected document information, and manages the digital signature and partial identification information related to the corrected part of the document information in association with the corrected document information. At the verification time, the program uses partial identfication information, the partial identification information corresponding to a corrected part of the document information before correction, and digital signature to perform verification.
