Residue transfer for encrypted messages split across multiple data segments

摘要

A method and apparatus for processing incomplete SSL/TLS records is disclosed. Typical processing of encrypted and authenticated SSL/TLS records involves reconstructing the entire record after if has been segmented by a transport layer in order to be sent over a networked connection. This creates a significant performance bottleneck. The disclosed invention takes the truncated records as they arrive and creates block-aligned segments (truncated records), coupled with residue left to transfer between an arriving segment and the previously block-aligned segment, which allows continuous processing of the encrypted partial records.
