Abstract: The present invention provides optimized enveloping for a public key cryptography system. A sender may reuse a secret key in multiple communications to a recipient without the need to recompute or re-encrypt the secret key. The first time a message is sent to a recipient, the sender generates and encrypts a secret key, then stores the secret key, the encrypted secret key, and associated counter data in a local data store. For subsequent messages to the recipient, the sender determines from the counter data whether the secret key may be reused; if the secret key is reused, the sender updates the counter data. A recipient stores previously received secret keys in a local data store in both encrypted and decrypted form. If an encrypted secret key in a received message matches an entry in the local data store, the recipient uses the previously decrypted secret key to decrypt the message.

Abstract: A method for transferring messages across a communication network is disclosed. A message being received at a message source from a sending application program is segmented into message segments. While this segmentation is occurring, a common message identifier and a unique sequence number are assigned to each message segment. The message segments are transferred from the message source to a message destination, with at least one of the message segments being transferred as the message is being received at the message source. Prior to the entire message being received at the message source and segmented, message segments that have already been segmented from the message are transferred to the message destination. At the message destination, the message segments are received and assembled into a reassembled message A portion of the reassembled message is delivered to a receiving application while the assembling is occurring.

Abstract: The present invention relates to relates to the efficient and secure transfer of information over a distributed computer network such as the Internet. The system provides parallel communication paths between the source and destination. Each path includes a dedicated route point to eliminate intermediate ISPs. Each source is associated with an archive and each route point is coupled to the archive. Upon receipt of the message at a route point the message is copied to the archive and then transmitted to the destination. Message archival and storage of transmission-related information enables data-mining features not presently available using email or a point-and-click browser. Since two messages are transmitted from the source to the common destination across separate and distinct communication paths, message latency is improved and the chance of lost messages is reduced or even eliminated.

Abstract: The present invention provides a system and method allowing businesses to send electronic messages, or other information, to conduct business over a digital network such as the Internet. Aspects of the system provide for a secure transfer of messages, tracking, monitoring, archiving, automated responses, statistics gathering and other features. The system provides a plurality of route point processors for routing messages independently of the Internet service providers (ISPs) routers and a unique forking algorithm whereby duplicate messages are generated and transmitted along separate communication backbones. Messages are archived at an intermediate point in the transmission path. The archival system and method provides a distributed archive that stores messages to guarantee message delivery to the destination, assists in message recovery and retains statistical information regarding the routing and delivery of the messages for subsequent access.

Abstract: A method for transferring messages between a sending application program and a receiving application program across a distributed communication network (e.g., the Internet) that includes a message source coupled to a message destination. The method includes segmenting a message (e.g., a relatively large message of one gigabyte or more) being received at the message source from the sending application program into a plurality of message segments. While this segmentation is occurring, a common message identifier and a unique sequence number are assigned to each of the plurality of message segments. The method also includes transferring the plurality of message segments from the message source to the message destination, along with the common message identifier and unique sequence number assigned to the plurality of message segments, with at least one of the plurality of message segments being transferred as the message is being received at the message source.
