Design and Verification of Pipelined Trivium Cipher

Cryptography and ciphers are essential for secure communication and data security. In order to ensure secrecy and integrity, plain text is converted into ciphertext using mathematical procedures and techniques. A type of symmetric encryption known as stream ciphers encrypts data bit by bit, usually in real time. Through this research, we have tried to design a new cipher technique that uses the pipelining concept to consume less power while taking up less space than conventional ciphers. Pipelined trivium ciphers are more efficient for ASIC implementation and can be placed in IP formats with ASIC implementation at online security services like blockchain technology. They are implemented based on the structure of conventional trivium ciphers and focused on reducing propagation delay to operate at a higher speed than conventional trivium ciphers. In order to attain excellent performance while consuming less energy, brand-new synchronous stream ciphers called pipelined trivium ciphers are developed by the team through this research work for security systems and online services. The designed pipelined trivium cipher is 1.18 GHz faster than the conventional trivium cipher with its slack value greater by a difference of 55 ps than the conventional trivium cipher.
