摘要:
Wireless communication method and apparatus which can perform the wireless transmission/reception of encrypted data without previous provision of a cryptographic key and without any system for registering a cryptographic key. Under control of a communication control section 504 in PC 1, the PC 1 transmits its own identification information to a printer 2 and receives identification information of the printer 2. The PC 1 has an encrypting/decrypting section 502 which generates a cryptographic key by using the identification information of the printer 2 and its own secret algorithm read out of an identification information storage section 510. According to a cryptographic program using such a cryptographic key, data is encrypted and transmitted toward the printer 2.
摘要:
A contactless data communication system includes a reader-writer device, a contactless identification tag including a plurality of contactless identification tags, and baggage including multiple pieces of baggage. The reader-writer device includes a data reception part, a data transmission part, a control part, an operation part, and a display part. The contactless identification tag includes a data communication part, a data control part, a voltage monitoring part, a detachment detection part, a display processing part, and an electrophoresis display device. The voltage monitoring part and the detachment detection part detect a voltage change caused when the contactless identification tag is detached from the baggage, so as to detect that the contactless identification tag is detached.
摘要:
A storage device includes a data storage unit storing a virus pattern of a computer virus, a virus data detection unit for detecting with use of the virus pattern as to whether data as a target to be written contains the virus, and a controller for enabling writing of the data into the data storage unit in the case where the virus data detection unit does not detect the virus.
