Abstract: A communication apparatus includes a communication unit having a first storage area of a predetermined size in which access from another apparatus is permitted and a second storage area of the predetermined size in which access from the other apparatus is permitted, and an encryption unit to generate concatenated encrypted data by using a block encryption method to encrypt a plurality of pieces of data which are to be read out by the other apparatus and encrypted. Data different from the concatenated encrypted data is held in the second storage area, and the concatenated encrypted data generated by the encryption unit is of a size not exceeding the predetermined size and is held in the first storage area. In addition, the size of padding data included in the concatenated encrypted data is smaller than a total size of padding data generated by individually encrypting the plurality of pieces of data.

Abstract: A job for executing predetermined processing is received from an external apparatus. When the job is received, the predetermined processing is executed. A setting value to be used to execute the predetermined processing is stored in a memory from which an external apparatus can read out the setting value even if no power is supplied to a communication apparatus.

Abstract: This invention provides a technique in which even if a job by a processing apparatus is interrupted during execution, another apparatus continues the processing using completely the same function without further billing the user. Upon receiving a print job, a printing apparatus executes billing processing for the job, in which the printing apparatus communicates with a billing server. The printing apparatus writes, in the memory of an NFC unit, setting values about the received print job, the identification information of the printing apparatus itself, and the identification information of another alternative processing apparatus. While executing the print job, the printing apparatus writes progress information about an unprocessed portion of the job in the memory of the NFC unit every time a preset processing unit is executed during execution of the job.
