Such security concerns have driven efforts to provide secure networking protocols, such as Internet Protocol (IP) security, or IPSEC, promulgated by the Internet Engineering Task Force (IETF) (see IPSEC proposals at Internet location <a href="http://www.ietf.org/ids.by.wg/ipsec.html.)">http://www.ietf.org/ids.by.wg/ipsec.html.)</a> This modified IP protocol refers to encrypting IP data traffic with large key lengths and complex encryption algorithms.
