Input data is compressed using a dictionary-based lossless data compressor before encryption then two elliptic curve cryptographic algorithms can be applied to the compressed data ECIES for encryption or ECDSA for digital signature. Applying data compression presents three advantages first the improvement in the cryptographic module throughput by reducing the amount of data to be encrypted second the higher utilization of the available bandwidth if encrypted data is transmitted across a public network and third the increment of the difficulty to recover the original information. The architecture was described in VHDL and synthesized for a Xilinx FPGA device. The results achieved show that it is possible to combine these two algorithms in a single chip while gathering the advantages of compression and cryptography. This work is novel in the sense that no such algorithm combination has been reported neither a hardware implementation of elliptic curve cryptographic schemes. 1. Introduction Data compression and cryptography play an important role when transmitting data across a public computer network. While compression reduces the amount of data to be transferred or stored cryptography
