    Abstract: If the related secure communication method is applied to the system which includes a plurality of the MTC devices, traffic in a network would increase in proportion to the number of MTC devices. A disclosed communication apparatus is connected to a network and a plurality of communication terminals, and includes: a group information sending unit for sending group information, which is received from the network; an access control unit for 1) receiving a reply from the communication terminal(s) which responded to the group information and 2) sending the reply to the network; and a temporary identifier and group key sending unit for sending a temporary identifier and a group key to the communication terminal which responded to the group information, when the communication apparatus received the temporary identifier and the group key from the network.

    Abstract: According to an arrangement, a communication apparatus (30) is connected to a bus (90) in which a second bit has higher priority than a first bit, and the communication apparatus (30) includes an acquisition unit (32), a generation unit (33), and transmission unit (34). In the communicaiton apparatus (30), the acquisition unit (32) is configured to obtain first information. The generation unit (33) is configured to generate second information in which the first information is set at a predetermined position and a predetermined bit string including the first bit is set at a position other than the predetermined position. The transmission unit (34) is configured to transmit communication data including the second information.

    Abstract: A technique for generating a cryptographic key (120) is provided. The technique is particularly useful for protecting the communication between two entities (202, 302; 204, 304) cooperatively running a distributed security operation. The technique comprises providing at least two parameters (106, 108), the first parameter (106) comprising or deriving from some cryptographic keys (110, 112) which have been computed by the first entity (202, 302) by running the security operation; and the second parameter (108) comprising or deriving from a token (116) having a different value each time the security (114) operation is initiated by the second entity (204, 304) for the first entity (202, 302). A key derivation function is applied to the provided parameters (106, 108) to generate the desired cryptographic key (120).
