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： One embodiment of the present invention provides a system that facilitates access to encrypted data on a computing device based on a security-posture of the computing device. During operation, the system assesses the security-posture of the computing device upon which the encrypted data is stored. If the assessed security-posture meets specified criteria, the system provides the computing device with a key which enables the computing device to access the encrypted data.

摘要： A method for establishing a secondary communication channel between at least two computing devices over a network medium through use of a primary channel connects a first computing device with a first telephonic unit and a second computing device with a second telephonic unit. If the two telephonic units are in communication with each other over a primary channel, and communication channels are established between the computing devices and their respective telephonic units, then the first computing device transmits its location information to the second computing device over the primary channel. A connection is then established between the second computing device and the first computing device over a secondary communication channel.

摘要： One embodiment of the present invention provides a system that uses a portable security token (PST) to facilitate cross-certification between a first certification authority (CA) and a second CA, wherein the first CA and associated subscriber devices constitute a first public-key infrastructure (PKI) domain, and wherein the second CA and associated subscriber devices constitute a second PKI domain. During operation, the system uses the PST to transfer certification information between the first CA and the second CA, wherein the PST communicates with the first CA and the second CA through a location-limited communication channel. Next, the system uses the certification information to issue a cross-certificate to the first CA. Note that the cross-certificate is signed by the second CA. Finally, the system propagates the cross-certificate from the first CA to the associated subscriber devices in the first PKI domain, thereby allowing the associated subscriber devices in the first PKI domain to authenticate themselves to the devices in the second PKI domain.

摘要： One embodiment of the present invention provides a system that uses a portable security token to facilitate public key certification for a target device in a network. During system operation, the portable security token is located in close physical proximity to the target device to allow the portable security token to communicate with the target device through a location-limited communication channel. During this communication, the portable security token receives an authenticator for the target device, and forms a ticket by digitally signing the authenticator with a key previously agreed upon by the portable security token and a certification authority (CA). Next, the portable security token sends the ticket to the target device, whereby the target device can subsequently present the ticket to the CA to prove that the target device is authorized to receive a credential from the CA.

摘要： System and method for enabling arbitrary components to control communications without having or requiring prior knowledge of each other. The system includes a first component that creates controller objects and provides the objects to other components. The controller objects include instructions which when executed by the other components enable the components to generate user interfaces for controlling the first component. Further, the controller objects are encrypted and are used to authenticate the senders or receivers of the objects.
