Blockchain plays a vital role in enabling users to securely communicate with reliability and transparency. Cryptographic hashing is the underlying structure of blockchain empowering cryptocurrencies. With the rapid advancement of communication network, cipher algorithms are becoming increasingly important in information security. Multimedia data are widely used in various applications, including health sectors, military, entertainment, education, banking, and communication with recent improvements in internet technologies. Meanwhile, the application background for cipher algorithms is becoming gradually more complicated, posing problems to existing systems and necessitating the development of new appropriate designs. Stream cipher has been a prominent research area in cryptography, and it is appropriate for use in circumstances of huge data transmission or resource limits. This work provides a quick overview of conventional encryption algorithms based on stream ciphers and cryptographic prerequisites. At present, several attacks faced by stream cipher techniques are also discussed.
