HARDWARE IMPLEMENTATION OF THE WALSH-RADEMACHER FUNCTIONS FOR COMMUNICATION SECURITY

Encoded data by Walsh sequence formed a primary step to generate encoded data to be inputs for ciphers. The encoded function is based on Walsh sequence generator. Rademacher functions which are stored in the device and a counter to produce the index of Walsh sequence which is used as inputs of Gray code function are generating Walsh sequence. In this work, we provide a Field Programmable Gate Array (FPGA) hardware implementation of this encoded data including Walsh sequence generator.
