PROBLEM TO BE SOLVED: To provide a communication apparatus capable of reducing processing load by dynamically changing setting without interrupting encryption communication for a long time. SOLUTION: The communication apparatus 1 includes an ROM 13 for storing a plurality of items of encrypted information and encrypted algorithms, a security processor 21, and a load monitor 22 for monitoring at least the processing load in the processor 21. If the processing load monitored by the monitor 22 reaches a prescribed level set in advance, the communication apparatus 1 changes the encrypted information or the encrypted algorithms, for example, for each terminal device 2 or for each communication data, or stops encryption processing, thereby reducing the processing load of an encryption processing means.
