OTIP: One Time IP Address

One Time IP address (OTIP) is a security feature to protect private communications on the Internet. OTIP enables nodes to change their IP addresses periodically following a cryp- tographic sequence. Legitimate users have all the information needed to compute the current addresses used by the servers, thus their networking clients are able to access the required services. OTIP current address is the output of a computation based on the Fully Qualified Domain Name (FQDN) of the server, a secret password and the current time. The major achievement of OTIP is that all the IP addresses collected by wiretapping the networks are useless for attackers as, in a short time, all the servers will be using different addresses.
