    摘要: The present invention provides a technology of effectively avoiding tracing on a terminal performed with an identification number being a target and DoS attack without making any significant changes to a communication system.In the wireless communication system of the present invention, under a control of a control communication processing portion 113 of an access point, a hash function arithmetic operation processing portion 112 generates a third identification number to be updated using a current identification number, hash key and random number for any wireless communication terminal, a control communication processing portion 113 sends an update instruction signal containing the random number to the wireless communication terminal and updates the current identification number stored in the identification number storage portion 121 to a second identification number. When the wireless communication terminal receives an update instruction signal, the current identification number is updated to the second identification number and the hash function arithmetic operation processing portion generates a third identification number using the current identification number, hash key and random number stored in the self number storage portion.

    摘要: A decentralized key management scheme that implements key management of a tree structure comprised of only group members without using a key management server is proposed, and communication method and system that can contribute to secure group communications is provided. Each member constituting a group updates tree structure data of the entire group when a new member joins, respectively 70, and selects a captain in each subtree 71. Rather than the key management server, the captain generates a new key and shares it with other captains or the joining member 72, and distributes the new key to the members of the subtree 73, thereby enabling all the group members to update to the new key. A captain is also selected when a member leaves, and sharing and distribution of a new key by the captain is performed.

    摘要: A low cost and high speed AF sensor is realized by increasing AF speed without providing a sensor dedicated for a large de-focusing AF. The AF sensor has two sensors each including a plurality of photoelectric conversion elements and detects a focus based on signals read from the sensors. The two sensors each includes a plurality of linear sensors 11 to 13. The two sensors each has a plurality of accumulation controlling circuits (PB detection circuits 14 to 16 and accumulation decision circuits 17 to 19) for controlling the accumulation time of the photoelectric conversion elements and a plurality of scanning circuits (shift registers 21 to 23) for reading out output signals from the photoelectric conversion elements. The AF sensor has a first mode in which the accumulation time of each linear sensor in the two sensors is independently controlled to independently read a signal output and a second mode in which the accumulation time of the linear sensors in the two sensors is collectively controlled to read a signal output.
