The key exchange method, public key algorithm, symmetric encryptionĪll negotiated. Parameter negotiation, and to minimize the number of round-trips. The protocol has been designed to be simple and flexible to allow User authentication can be designed on top of this protocol. It provides strong encryption, cryptographic host authentication, andĪuthentication in this protocol level is host-based this protocolĭoes not perform user authentication. The SSH transport layer is a secure, low level transport protocol. RFC 4253 SSH Transport Layer Protocol January 2006 1. RFC 4253 SSH Transport Layer Protocol January 2006ġ. This document also describes the Diffie-Hellman key exchange methodĪnd the minimal set of algorithms that are needed to implement the Key exchange method, public key algorithm, symmetric encryptionĪlgorithm, message authentication algorithm, and hash algorithm are
It provides strongĮncryption, server authentication, and integrity protection. The protocol can be used as a basisįor a number of secure network services.
