A transmissive color liquid crystal display including a first liquid crystal section, a light-guiding element, a second liquid crystal section, and first and second liquid crystal drivers. The first liquid crystal section presents color images. The light-guiding element is situated behind the first liquid crystal section for orienting rays toward the first liquid crystal display section. The second liquid crystal section includes a plurality of zones capable of transmitting wavelength bands of external rays, respectively. The zones are selectively activated for introducing colored external rays through respective zones to the light-guiding element. The first liquid crystal driver controls the first liquid crystal section. While color-component data extracted from full color image data is input into the first liquid crystal driver in a time-division manner, the first liquid crystal driver activates and deactivates pixels on the first liquid crystal section for presenting images on the first liquid crystal display on the basis of the color-component data in time division manner. The second liquid crystal driver selectively activates the zones in the second liquid crystal section in time division manner for introducing colored external rays of which wavelength bands correspond to the color-component data through the zone to the light-guiding element for irradiating the images on the first liquid crystal section with the colored external rays in time division manner.

An object of the present invention is to provide a color image display apparatus which can easily display a full-color animation of VGA class and attains reduction in size and lowering of price and which facilitates full-color gradation control. In order to achieve the object, a color image display apparatus includes a shutter control circuit that slices color component data subjected to color separation in accordance with a slice level, a light source control circuit that controls a light source corresponding to the color component data, one or plural light sources a converting device that converts light from the light source to surface light source light, a shutter which makes light of a corresponding pixel pass therethrough and cuts off the light and which is made of liquid crystal as a main material, and a timing circuit that generates operation timings for the shutter control circuit and the light source control circuit, in which the shutter control circuit transfers one line of slice data to the shutter sequentially on a slice level basis, the light source control circuit turns on the light source corresponding to the source data, and the shutter makes the light from the light source, which corresponds to the slice data representing gradation of the pixel, pass therethrough and cuts off the light to display an image.

It is aimed, for example, to reduce an amount of power consumption of an operation concerning data encryption or decryption and to make it difficult to perform a power analysis. In the case an exclusive OR operation between 32-bit input data and a 32-bit key is performed to obtain output data of 32 bits, the input data is kept in an input shift register 105 of 32 bits and the key is kept in a key shift register 106 of 32 bits. Then, 1 bit of the input data and 1 bit of the key are input into a serial operator 107, and an exclusive OR of 1 bit is obtained and shifted to the left end of the input shift register 105. The key shift register 106 performs a cyclic right shift. By performing the above thirty-two times, the operation of 32 bits is completed and the last result is kept in the input shift register 105.

This invention relates to an encryption communication apparatus using encryption processing. It is an object of this invention to obtain the encryption communication apparatus with excellent tamper-resistance while ensuring sufficient securities. A communicating unit 1 sends and receives communication data including a length field and a data field. A length comparing unit 6 compares a value of the length field and a minimum length value stored in the apparatus in advance. When it is judged that the value of the length field is less than the minimum length value, a controlling unit 7 controls an encryption processing unit 5 not to perform encryption processing or decryption processing of the data in the data field.

A flowchart shows a general processing procedure of cryptographic computation executed by a cryptographic computation apparatus 100. A power supply is turned on in S101. In S102, a cryptographic computation execution program is fetched, and initialization such as memory allocation is performed. In S103, a plaintext is input, and the plaintext is stored by a RAM or the like. In S104, the cryptographic computation execution program is fetched, and the cryptographic computation is performed using a resistor or the RAM. In S105, a ciphertext is extracted. In S106, a CPU determines whether or not to continue a cryptographic computation process. In case of continuation, the flow returns to S102. In the above encryption process of S102 through S106, a resistor/memory input process (S200) is interposed between S103 and S104. In S200, before the cryptographic computation (S104) is started, data (e.g., a plaintext) that changes for each cryptographic computation is written in a register or memory to be used for the cryptographic computation. Then, the cryptographic computation is performed.
