Method for providing secure access to information held in a shared repository
A method for providing secure access to information held in a shared repository, for example to electronic business cards stored on a server. A data owner registers with the server and provides information to be shared with selected data users. The server returns public-key cryptography keys. To access the information, a data user sends its public key to the data owner. The data owner encrypts the public key using the data owner private key, and sends the result to the server, along with permission to transfer information to the data user. The server decrypts the received result using the data owner public key, and compares the outcome with the data user public key. If they match, the server records permission on an access list. In response to a request for information the server checks the access list to determine whether the data user has permission. If so, the server encrypts the information using the data user public key, and transfers the result to the data user.

Secure access to remote resources over a network
A client computer hosts a virtual private network tool to establish a virtual private network connection with a remote network. Upon startup, the virtual private network tool collects critical network information for the client computer, and sends this critical network information to an address assignment server in the remote network. The address assignment server compares the critical network information with a pool of available addresses in the remote network, and assigns addresses for use by the client computer that do not conflict with the addresses for local resources. The address assignment server also provides routing information for resources in the remote network to the virtual private network tool. The virtual private network tool will postpone loading this routing information into the routing tables of the client computer until the client computer requests access to a specific resource in the remote network. When the client computer requests access to a specific resource in the remote network, the virtual private network tool will only provide the routing table with the routing information for that specific remote resource.

Receiver-driven layered error correction multicast over heterogeneous packet networks
A system and method for correcting errors and losses occurring during a receiver-driven layered multicast (RLM) of real-time media over a heterogeneous packet network such as the Internet. This is accomplished by augmenting RLM with one or more layers of error correction information. This allows each receiver to separately optimize the quality of received audio and video information by subscribing to at least one error correction layer. Ideally, each source layer in a RLM would have one or more multicasted error correction data streams (i.e., layers) associated therewith. Each of the error correction layers would contain information that can be used to replace lost packets from the associated source layer. More than one error correction layer is proposed as some of the error correction packets contained in the data stream needed to replace the packets lost in the associated source stream may themselves be lost in transmission. A preferred process for generating the error correction streams involves the use of a unique adaptation of the Forward Error Correction (FEC) techniques. This process encodes the transmission data using a linear transform which adds redundant elements. The redundancy permits losses to be corrected because any of the original data elements can be derived from any of the encoded elements. Thus, as long as enough of the encoded data elements are received so as to equal the number of the original data elements, it is possible to derive all the original elements.
