摘要： A transmitting apparatus transmits, to a receiving apparatus, a content that contains at least, in the stated order, a first portion that is encrypted with a shared key shared between the transmitting apparatus and the receiving apparatus, a second portion that is not encrypted, and a third portion that is encrypted with the shared key. In this situation, in the case where the encrypted third portion has become a transmission target after the second portion has been transmitted, and also, there is a possibility that the shared key stored in the receiving apparatus may be invalidated when the encrypted third portion is received, the transmitting apparatus sequentially transmits a fourth portion and the encrypted third portion to the receiving apparatus, the fourth portion containing at least element data that belongs to the last group in the second portion.

摘要： In an information processing system in which a range of information transfer between communication devices through a network is limited within a prescribed range by registering unique information obtainable within the prescribed range into each device and permitting information transfer between devices which share common unique information, where the unique information is formed by a pair of a public unique information and a secret unique information, a bridge device is controlled such that, upon receiving a proxy check request from a reception device, whether a transmission device is another bridge device or not is judged when the public unique information registered by the reception device is registered in the bridge device and one public unique information registered in the bridge device is registered by the transmission device. Then, the secret unique information registered by the reception device is transmitted to the transmission device when the transmission device is not another bridge device.
