ABSTRACT:
A method and system for selectively interconnecting a plurality of computers (112,114) over an open public network (120,102,122), such as the INTERNET, provides a private secure computer exchange of EDI interchange communications between a sender computer (112) and a recipient computer (114), each of which has an associated public key and an associated private key, such as in an RSA type cryptographic communication system (100). The associated EDI acknowledgement message, such as the AUTACK, is used to provide secure authentication and non-repudiation of both origin and receipt of the secure private EDI interchange communications transmitted over the open public network (120,102,122) with the AUTACK transmitted from the sender computer (112) being digitally signed with the sender's private key, and with the reply AUTACK transmitted from the recipient computer (114) being digitally signed with the recipient's private key. The respective digitally signed AUTACKs are decrypted after receipt by using the public key associated with the private key used to provide the digital signature. The transmitted AUTACK from the sender computer (112) includes an MD5 for the entire EDI interchange as well as an MD5 of the AUTACK, with the AUTACK, thus, being used to provide the digital signature. The reply AUTACK from the recipient computer (114) includes an MD5 of the reply AUTACK. The ability to conduct business over the network (120,102,122) is controlled by private trading partner agreement communications which provide key certification.
