    摘要: A system and method for sharing files securely includes server software on a first device configured to communicate with server software operating on one or more other preauthorized devices, such as a second device. The servers communicate with each other securely using cryptographic information exchanged during a preauthorization phase using a range-limited communication channel. The server on the first device obtains file information from the other preauthorized device(s) and combines the information with local file information from the first device. This combined file information is sent to client software operating on the machine, which presents the combined file information to users.

    摘要: Pre-authentication information of devices is used to securely authenticate arbitrary peer-to-peer ad-hoc interactions. In one embodiment, public key cryptography is used in the main wireless link with location-limited channels being initially used to pre-authenticate devices. Use of public keys in the pre-authentication data allows for the broadening of types of media suitable for use as location-limited channels to include, for example, audio and infrared. Also, it allows a range of key exchange protocols which can be authenticated in this manner to include most public-key-based protocols. As a result, a large range of devices, protocols can be used in various applications. Further, an eavesdropper is forced to mount an active attack on the location-limited channel itself in order to access an ad-hoc exchange. However, this results in the discovery of the eavesdropper.
