摘要： When processing a data conversion function of a MISTY structure, such as the FO function of MISTY1, the logical calculation result t3 of the exclusive OR 614 of the process result of the FI function 602 of the MISTY structure in the second stage and a logical calculation result t1 of an exclusive OR 612 of the MISTY structure in the first stage is not stored in a register. The logical calculation result t3 and the logical calculation result of respective exclusive OR 642 and 643 are subject to a direct exclusive OR with the respective exclusive OR 642 and 643.

摘要： Ciphertext X and a constant C having relationships C>p and C>q with respect to secret keys p and q are input, and correction values C−dp and C−dq (dp=d mod (p−1), dq=d mod (q−1)) are obtained. Then, the ciphertext X is multiplied by the constant C. A remainder operation using the secret key p or q as a remainder value is conducted with respect to the multiplication result. A modular exponentiation operation based on a Chinese remainder theorem is conducted with respect to the remainder operation result, and a correction operation using a correction value C−dp or C−dq is conducted. Thereafter, plaintext Y before being encrypted is calculated.

摘要： A peak of the radiation directivity of light emitted by each of LEDs is directed to a reflecting surface, and the light emitted by the LEDs is indirectly incident on an outer lens after reflection by the reflecting surface. Thus, problems, such as a local increase in brightness of a light emitting surface over areas corresponding to light emitting portions of the LEDs, are prevented. In addition, most of the light emitted by the LEDs is indirectly incident on the outer lens via the reflecting surface, so that dispersion of blue light and yellow light, which constitute the white light, by the outer lens is prevented. Thus, illumination light highly uniform in amount and color can be provided.
