摘要： A data writing method for writing data to a flash memory includes writing an initial value to the data storage area, determining whether or not the writing of the initial value is performed normally based on a write flag, writing data to the data storage area when the writing is performed normally, and erasing a block including the data storage area when the writing is not performed normally. An initial value is written to the data storage area before writing data, so that whether or not an error correction code storage area contains the initial value may be confirmed. An erase operation of the block is performed only when the error correction code storage area does not contain the initial value, so that the number of times of erasure of the block may be reduced and the life of the product may be increased.

摘要： An information transmitting apparatus encrypts and transmits transmit data that includes contents for which transmission instruction has been received, an authentication code, and padding. The information transmitting apparatus includes a padding calculating unit that calculates a size of the padding based on an encrypting algorithm, a size of the authentication code and a size of the contents; a transmit-data size calculating unit that calculates a size of the transmit data from the size of the padding, the size of the authentication code, and the size of the contents; a generating unit that generates, using the size of the transmit data, a header that indicates a type of the transmit data and the size of the transmit data; an encrypting unit that encrypts the transmit data; and a transmitting unit that transmits the header and the encrypted transmit data.
