摘要： In a data encryption/decryption method including an encryption step and a decryption step. In the encryption step, there are prepared n pairs of secret keys and public keys in a public-key cryptographic scheme, where n is a positive integer. A new key is generated in accordance with at least one of the public keys. Data is encrypted in a common-key cryptographic scheme by use of the new key. There is prepared a (k,n) threshold logic (k is an integer equal to or less than n) having terms associated with the new key and the n public keys. A calculation of the threshold logic is conducted by use of the new key and the n public keys, and encrypted data and a result of the calculation of the threshold logic are stored. In the decryption step, the new key is restored from k secret keys selected from the n secret keys and the stored result of the threshold logic calculation in accordance with a threshold reverse logic corresponding to the threshold logic and stored data is decrypted by the restored key in the common-key cryptographic scheme.

摘要： In an IC card incorporating residual multiplier hardware for implementing a high-speed algorithm for a residual multiplication arithmetic, a method and a device capable of executing public key encryption processing such as an elliptic curve encryption processing at a high speed. Residual arithmetic succeeding to generation of a random number and residual arithmetic in a signature generating processing can be executed by using a residual multiplier. Further, in order to use effectively the residual multiplier for arithmetic operation on an elliptic curve, the point on the elliptic curve is transformed from a two-dimensional affine coordinate system to a three-dimensional coordinate system. Additionally, multiplicative inverse arithmetic for realizing reverse transformation from the three-dimensional coordinate system to the two-dimensional affine coordinate system as well as for determining a signature s can be executed only with the residual multiplication arithmetic. By making use of the residual multiplier in this manner, the processing speed can be increased. Computation complexity can be reduced by storing previously those parameters which are used frequently and constant multiplies of a base point of the elliptic curve in the form of tables, which also contributes to increasing of processing speed.

摘要： According to a cryptographic communication system which can safely perform cipher conversion processing when cryptographic communication is performed between terminals using different cipher types, when a terminal 10A-1 connected to a LAN-A using a cryptographic algorithm C1 transmits data to a terminal 10B-1 connected to a LAN-B using a cryptographic algorithm C2, the terminal 10A-1 generates two meaningless data items from the data to be transmitted, decrypts the two generated data items according to the cryptographic algorithm C1, and then transmits the decrypted data to two cryptographic protocol conversion servers and for dividing the data into two data items. Each of the cryptographic protocol conversion servers decrypts each transmitted data item, the re-encrypts the decrypted data according to the cryptographic algorithm C2, and then transmits the data to the terminal 10B-1. The terminal 10B-1 restores original transmission data on the basis of the two data items transmitted from the respective cryptographic protocol conversion servers.

摘要： An identification code management method and management system includes that the issue and distribution of an ID code having a message authentication code are managed thereby to efficiently and reliably manage a material object using the ID code. An electronic circuit chip with an ID code having a message authentication code stored in a read-only area is used as an identification tag. The information at an ID code order receiving terminal and an identification tag production factory terminal are consolidated and collectively managed at an ID code management terminal. Thereby, the ID code management terminal is inquired of highly confidential information or requested to process the information as required so that an ID code utilization terminal is not required to store the same information.

摘要： A RFID tag structure determining the authenticity of an article, and an information processing system for reading RFID tags, enable authenticity determinations of articles using read only RFID tags. A plurality of RFID tags, each holding tag information inside ROM (read-only memory) and responding to tag information via a radio wave received from a reader, are designed to have a service identifier which designates a common utilization goal for which the same value is set, and service data which sets different values for the respective RFID tags, as tag information. By dividing the data structure of a RFID tag having a read-only memory into a service identifier, which is common to a certain product, and sequential data for managing individual products, it is possible to confirm that an article is authentic by simply confirming the service identifier.
