Simple Key-management for Internet Protocols. SKIP is a public key certificate-based key-management scheme that provides key-management for Internet protocols. SKIP uses certified Diffie-Hellman public values, which obviates the need for pseudo-session state establishment and for prior communications between two participating ends in order to acquire and change traffic encryption keys. SKIP addresses the problems inherent in companies that have employees telecommuting from home, a sales force on the road working from laptops, or customers purchasing their products off the Web. The SunScreen SKIP allows employees, partners, and consumers to communicate with encryption, while protecting their data as they go out on the Internet. At this point, SunScreen SKIP works with Sun SolarisTM 2.4, 2.5, and 2.5.1 and Solaris for the Intel Platform.
