A method of securing a local link may involve exchange of initiation messages and negotiation of ciphersuites across a local link. The method then transmits a server authentication and receives a client authentication. Upon validation of the server and client authentication, information from the cipher is used to encrypt communications across the local link. In addition, there is a method of providing intra-platform security. The method performs authentication between two endpoints on a platform and then generates keys between the two endpoints to form a trusted tunnel. The keys are used to encrypt communications between the endpoints.
