DES (Data Encryption Standard) is one such encryption algorithm used mainly in financial and commercial applications. AES (Advanced Encryption Standard) , RC5 (Rivest Cipher 5), RSA : These are some ...

RC5 block cipher is based on RC5 encryption algorithm. The parameter of RC5 encryption algorithm taken are word (w) = 32, round(r) = 4 and key (k) = 128. The simulation is done on Aldec Active HDL.
