Abstract: In response to receiving an unknown first session identifier from a client for a first communication session between the client and a server, a Man in the Middle (MitM) computer requests a second session identifier from the server for a second communication session between the server and the MitM computer. The MitM computer generates a third session identifier for a third communication session between the MitM computer and the client. The MitM computer generates a fourth communication session between the server and the client using a combination of the second communication session and the third communication session. In response to receiving an invalid session identifier from the client for a fifth communication session between the client and the server, the MitM computer transmits an instruction, to the client, to flush a session cache in the client to force a full TLS handshake between the client and the server.

Abstract: Techniques for reducing the latency for decoding product codewords with minimal hardware architecture changes are described. In an example, multiple decoding procedures are available a system. The system maintains decoding states. Each decoding state corresponds to a constituent codeword of a product codeword and to a decoding procedure. For instance, a BCH decoding state indicates whether the decoding of the respective BCH constituent codeword has previously failed. The decoding of the product codeword depends on the various decoding state. For instance, in a BCH decoding iteration, if a BCH decoding state of a constitutent codeword is set to “failed,” the BCH decoding of that codeword is skipped.
