A method, system and apparatus are described for avoiding the use of a
web-server or generic security when providing network administration
services remotely to managed entities using wireless technology. Instead
a true Proxy device, not operating as a web-server, is used to preprocess
all command traffic from wireless input devices (WID). The intervention
between the WID and the managed entities of the Proxy isolating the
managed entities from the WID, enhanced by encoding using a novel
messaging protocol, further enhanced by a novel security model based on
multiple pre-shared keys and algorithms together with identifiers and
passwords that are not transmitted, achieves several bandwidth and
security advantages including the ability to deliver TELNET services
across the Internet and behind a firewall.
