Abstract

An electronic system for secure tendering over an open network until close of tendering is provided. In order to be permitted to file a bid electronically in response to an invitation to tender, prospective vendors encrypt their bid proposals using session keys obtained from a third party source. The encrypted proposals are filed with the bid requester who does not have access to the session keys while the tendering period remains open. The encrypted bid proposals are cached in a safe repository until close of tendering. In one embodiment, the bid requester itself holds onto the encrypted proposals, and obtains the session keys for accessing their contents from the third party on expiry of the bid submission period. In another embodiment, the bid requester double-encrypts each encrypted bid proposal as it is received using its own privately-held key, and forwards the double-encrypted proposals to the third party to hold in a safe repository until the close of tendering. The third party then returns the double-encrypted proposals to the bid requester along with the session keys to permit the bid requester to access their contents. In either case, the party that caches the bid proposals until the close of tendering does not have access to the key required to decrypt the proposals.
