Modified Double Mod RSA Tested with Brute Force Attack

Rivest Shamir and Adlemen (RSA) cryptosystem, an asymmetric cryptosystem uses single modulus function for encryption and decryption with different key, hence asymmetric. The key to decryption is using private key that can be created from the public key and modulus using modulus inverse, extended Euclidean method. We modified the RSA using double modulus function to increase the security. After which we applied brute force attack which is more prevalent in the insecure network. There were 3 transmissions between the sender and receiver for the same message. We tested the RSA security using brute force attack on final transmission where the receiver is getting the final message. We got around 12 character match from the original plain text. Which forces, further security in RSA needs to be implemented. We defined keys of size 32 bits and modulus in range from 16-32 bits.
