An Interactive Data Exchange Protocol Based on Discrete Exponentiation

In this paper, we have described a protocol for interactive data exchange which provides strong mutual authentication of the users and data integrity. The protocols used are based on a cryptographic system using discrete exponentiation for public key exchange and conventional data exchange. The protocol is robust to data/protocol errors and active attacks. While it has been shown as an interactive protocol, a one-way data exchange protocol (for email or file transfer) can easily be derived from this protocol.
