An implementation of inter-organization cryptosystem based on RSA cryptosystem

Conventional cryptosystems are supposed to be used for the personal communication. However, the secure and effective communication system is more and more required for inter-organization cryptosystem. In this paper, we redefine the inter-organization cryptosystem using the public-key cryptosystem. We also propose an effective scheme of inter-organization cryptosystem using two of the RSA cryptosystems. We then implemented the prototype of the proposed scheme.
