In this paper we propose a pure hardware implementation of a key agreement protocol which uses the elliptic curve Diffie-Hellmann and digital signature algorithms and enables two parties a remote agent and a networked embedded system to establish a 128-bit symmetric key for encryption of all transmitted data via the advanced encryption scheme AES . The resulting implementation is a protocol-on-chip that supports full 128-bit equivalent security PoC-128 . The PoC-128 has been implemented in an FPGA but it can also be used as an IP within different embedded applications. As 128-bit security is conjectured valid for the foreseeable future the PoC-128 goes well beyond the state of art in securing networked embedded devices. Copyright 2007 Roshan Duraisamy et al.
