Abstract
In procurement system, either paper-based or electronic, the seller should submit documents to the buyer. The documents are usually restricted and confidential, containing information that should only be read by purchasing committee, never be read by any other parties, especially the competitors. Therefore special treatment to hide the confidentiality should be applied to the documents envelope, so that the system can meet the required information security principles such as authentication, integrity, confidentiality and non-repudiation. In this paper a method to create electronic secure envelope containing e-procurement submission document is proposed. Asymmetric Cryptosystem using RSA Algorithm is used to develop a document submission system. Before the submission process, the seller should authenticate himself using his private key. Documents to be submitted will be compressed with a random session/envelope key. The session key will be sealed with both private key of the seller and the public key of purchasing committee so that anyone else can decrypt the encrypted documents. The submission process is performed using upload capability of hyper-text transmission protocol (HTTP).
