  • Publication number: 20110188652
    Abstract: An encryption part (103) inputs a picture data packet (110) including I slice data which is used for intra-frame prediction and a processing on which starts from leading data at a time of data decompression. The encryption part (103) extracts, from the leading portion of the I slice data, data having a data size sufficiently small compared to the data size of the I slice data as a whole, and encrypts only the extracted leading data. Intra-frame prediction cannot be performed when the leading data of the I slice data is not decrypted. Therefore unauthorized decryption and reproduction of motion picture data can be prevented with encryption of a small amount of data.

  • Patent number: 7949807
    Abstract: 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.

  • Patent number: 7899418
    Abstract: A mobile device is equipped with a transmitting function to transmit data. When a power switch is turned off during data transmission, a transition is made to a transmission-during-power-off mode that continues data transmission. The transition to the transmission-during-power-off mode is performed when an inquiry is made on a screen as to whether transmission will be performed and “continue” is subsequently selected. In this mode, even when the mobile device with the power switch being turned off is carried around, data transmission is continued and data is recorded into a storage section of a home personal computer.

  • Publication number: 20110022852
    Abstract: 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.

  • Patent number: 7646427
    Abstract: A mounting board of a camera module of a mobile phone is screwed to an outer cover through cushions formed of rubber, sponge or the like. A solid state imaging device and an optical unit of the camera module are contained in an opening formed in the outer cover and do not contact the outer cover. The mounting board is connected to a main substrate through a flexible board. Accordingly, even if the mobile phone is dropped down, the camera module is prevented from breakage by the vibration or the shock applied to the mobile phone, because the vibration and the shock are not transmitted to the camera module directly.
