ABSTRACT:
During connection establishments for a protocol with bidirectional identifiers, connection data is allocated, the locally selected identifier is a pointer to the allocated connection data, and a mathematical transformation is applied to the pointer. The pointer and a result of the mathematical transformation are included in a first and second portion of the connection establishment packets respectively. Upon receipt of a data packet for that protocol, a first and second portion of the data packet (which correspond to the first and second portion of the connection establishment packets) are extracted. The same mathematical transformation used during connection establishment is applied to the data extracted from the first portion of the data packet. The result of that mathematical transformation is compared with the data extracted from the second portion of the data packet. If the values match, then the data extracted from the first portion is trusted and dereferenced to access the allocated connection data associated with that data packet.
