Secure Multicarrier Filter Bank Based Modem on FPGA

The paper deals with the design and realization of a secure Filter Bank Based (FBB) multicarrier modem on FPGA. The theory and realization of a multicarrier filter bank based modem are presented in brief. Then the crypto-modem principle is adopted. An encryption block is integrated in the modem transmitter and a decryption block is integrated in the modem receiver. Different Encryption/Decryption IPs (Intellectual Properties) implementing DES (Data Encryption Standard), 3DES (Triple DES) and AES (Advanced Encryption Standard) algorithms are developed and/or adapted in order to estimate the feasibility as well as the time and area efficiency of the crypto-modem.
