Latest Patents

One of Hsia R Yu's latest patents is titled "Anti-replay checking with multiple sequence number spaces." This invention involves processes and systems that create multiple sequence number spaces in a security association at a transmission device. Each sequence number space corresponds to a specific class of traffic and is identified by a unique selector value. For each space, a sequence number counter is established to count outbound packets of the corresponding traffic class. The invention ensures that for an outbound packet, the selector value of the relevant sequence number space is recorded in a designated portion of the sequence number field, while the low-order bits of the current sequence number counter are written into another portion. This method enhances the security of data transmission by preventing replay attacks.

Another significant patent by Hsia R Yu is focused on "Selecting a communications protocol." This invention outlines a method and system for selecting a communication protocol based on the type of address used by a mobile node. When an initial request with a static Internet Protocol address is received, a dynamic address is assigned to the mobile node. The system then determines whether the data packet from the mobile node uses the dynamic address or includes a mobile Internet Protocol request. Depending on this determination, the data packet is processed using either a mobile Internet Protocol process or a simple Internet Protocol process.
