Abstract
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.
