Abstract: Cryptography is used in various fields such as network communication, disk storage, user and equipment authentication. However, most cryptographic devices use block ciphers or public key ciphers and there are few instances of using stream ciphers. This can be seen as a question of the reliability and security of stream ciphers. In this study, we improve the speed of PingPong stream cipher and we have designed a hardware structure for single and multi-channel PingPong 256 where we implemented in the simulation: first, the original one path was extended to four to increase performance. Second, it changes the variable clock and feedback functions to assure the randomness based on the same initial value.
