If cipher suites using pre-shared keys are used for device authentication, the ISEC7 SPHERE must have a minimum security strength of 112 bits or higher, must only be used in networks where both the client and server are government systems, must prohibit client negotiation to TLS 1.1, TLS 1.0, SSL 2.0, or SSL 3.0 and must prohibit or restrict the use of protocols that transmit unencrypted authentication information or use flawed cryptographic algorithm for transmission.
