Abstract (en)
[origin: WO2008064153A2] One example embodiment of the present invention discloses a method for processing an application packet for transmission includes receiving a plurality of segments of the application packet in a byte stream, the byte stream including a plurality of blocks, creating a plurality of superblocks within the byte stream by grouping a number of the plurality of blocks within the byte stream, and creating first pseudorandom bits for the plurality of superblocks. The method also includes determining a block number and a superblock number for a beginning of each of the plurality of segments, determining a block number and a superblock number for an ending of each of the plurality of segments in the byte stream. The method further includes generating a partial tag for each of the plurality of segments in the byte stream based on the first pseudorandom bits associated with the block numbers and superblock numbers between the determined beginning and ending of the each of the plurality of segments in the byte stream, combining the partial tags including a last partial tag associated with a last segment of the application packet to create an accumulated tag, generating an authentication tag based on the accumulated tag and second pseudorandom bits, storing the authentication tag, and transmitting the plurality of segments including the authentication tag.
