SECURITY AND CERTIFICATE MANAGEMENT FOR ELECTRONIC BUSINESS TO BUSINESS TRANSACTIONS

Methods, systems, and devices are described for the secure electronic exchange of procurement documents. A server computer system may manage different sets of security procedures, distributing certificates to trading partners. These certificates may be community-specific certificates for a limited community of trading partners. When particular trading partners (e.g., of the community) agree to exchange procurement documents, they may first exchange their certificates (or portions thereof) with each other. A sending trading partner may then provide an electronic signature for a procurement document to be transmitted, and encrypt the signed procurement document using the receiving trading partner's public key.
