Abstract: A method for processing data of a security protocol comprises receiving a data packet associated to the security protocol over a network; determining, whether the data packet belongs to a group of post fragmented, PF, packets; processing the content of the data packet according to the security protocol if the data packet does not belong to the group of post fragmented packets; and forwarding the data packet if the data packet does belong to the group of post fragmented packets.

Abstract: Methods and apparatus for dynamic adaption of anti-replay window (ARW) management with enhanced security. According to aspects of the method, pre-ARW block employing a pre-ARW sliding window and an ARW block employing an ARW sliding window are maintained for an associated IPsec security association (SA). A determination is made to whether a received packet passes a pre-ARW check using the pre-ARW sliding window. When it does, the pre-ARW sliding window is advanced, encrypted content in the packet is decrypted, and processing is forwarded to the ARW block which performs an ARW check and advances the ARW sliding window when the ARW check is passed. Packets that do not pass the pre-ARW check may be buffered in queues and subsequently rechecked against the ARW sliding window. Under solutions provided herein, ARW checks and updates are decoupled from the decryption processes, enabling decryption to be performed in parallel and/or offloaded to a hardware accelerator.
