Abstract

The RSA system is widely employed and achieves good performance and high security. In this paper, we use Verilog to implement a 16-bit RSA block cipher system. The whole implementation includes three parts: key generation, encryption and decryption process. The key generation stage aims to generate a pair of public key and private key, and then the private key will be distributed to receiver according to certain key distribution schemes. Data security is achieved after the 64-bit input data are block encrypted by RSA public key. The c ....etc

In cryptography the only need of high importance is
security of data.Few ways to achieve it is through public
key cryptography(PKC),secret key cryptography(SKC) and
using hash functions. Generic PKC employs two keys that
are mathematically related although knowledge of one key
does not allow someone to easily determine the other key.
One key is used to encrypt the plaintext and the other key is
used to decrypt the ciphertext(encrypted data). Because a
pair of keys are required, this approach is also called
asymmetric cryptography. T ....etc
