Keyfusion Systems Inc. contact us Keyfusion is an Internet authentication protocol. It is designed to provide strong authentication for client/server applications by using public key cryptography. Keyfusion uses a patent pending method for securely distributing the private key and storing it on the client's browser plug-in. Keyfusion is an open source product available in both source and binary code under commercial and non-commercial licenses. Keyfusion is leading the way in open source developer tools for cutting edge solutions that bring trust to e-commerce. Our company is committed to securing e-commerce transactions over the Internet and wireless networks. Our products and services offer secure, trusted transaction assurance and real customer value for the Business-to-Consumer and Business-to-Business markets. The Keyfusion protocol uses strong cryptography so that a client can prove its identity to a server (and vice versa) across an insecure IP connection. After a client and server has used Keyfusion to prove their identity, they can also provide non-repudiation services. Part of the authentication process is the use of a digital signature as a method of providing transaction assurance. If you access the database you sign the network log when you enter and when you leave, if you buy a product or pay a bill online you sign the receipt, complete a business transaction you sign the contracts.
