摘要： The pseudorandom number generating system repeatedly performs simple transformation of a non-secure pseudorandom number sequence that may be generated quickly, and thus may quickly generate a highly secure pseudorandom number sequence having a long period. Furthermore, the encryption system and the decryption system do not generate a large encryption function difficult to be deciphered based on a shared key 122, but prepare multiple functions 126, which perform fast, different types of transformation, and select a combination of functions determined based on information of the shared key 122, and make the selected functions transform a text multiple times, thereby encrypt the text. Each of the functions is fast, and thus transformation by the entire combination is also fast. Furthermore, since the combination of functions and repetitive count can be changed, future improvement in specification is easy. Moreover, security is high since which functions are applied in what order is unknown.

摘要： An authenticating device authenticates a user by using an authenticating card having holes formed at positions unique to the user and has the following sections (A) to (C). (A) A random image creating section for creating a condition-meeting random image meeting the condition that at least one set of color unit images of the same color are present at positions corresponding to two holes when the authenticating card is placed over the images of colors randomly arranged. (B) A matching section for judging whether or not the color represented by answer information of the user is one of the colors of at least the one set of color unit images doubly viewed through the two holes of the authenticating card when the authenticating card is placed over eth condition-meeting random image (condition (b)). (C) An authentication judging section for judging that the user is successfully authenticated when the matching section repeats judgment repetition times RN meeting condition (c) mentioned below and judges that the color represented by the answer information meets condition (b) at all the repeated judgments. Condition (c): RN meets the condition that (G1/CN× . . . ×(GRN/CN) is a predetermined value or less where CN is the number of different colors, and Gi is the number of sets of color unit images of the same color present at two holes when the authenticating card is placed over the condition-meeting random image at the i-th judgment.

摘要： The present invention provides a pseudorandom number generating system, an encryption system, and a decryption system. The pseudorandom number generating system of the present invention repeatedly performs simple transformation of a non-secure pseudorandom number sequence that may be generated quickly, and thus may quickly generate a highly secure pseudorandom number sequence having a long period. In addition, the encryption system and the decryption system of the present invention do not generate a large encryption function difficult to be deciphered based on a shared key 122, but prepare multiple functions 126, which perform fast, different types of transformation, and select a combination of functions determined based on information of the shared key 122, and make the selected functions transform a text multiple times, thereby encrypt the text. Each of the functions is basically fast, and thus transformation by the entire combination is also fast. Furthermore, since the combination of functions and repetitive count for them can be changed, future improvement in specification is easy. Moreover, security is high since which functions are applied in what order is unknown.
