Historical Stream Ciphers totally on the secrecy of the secret key .. Although this well-established principle, called Kerckhoffs’ principle, has been known since the mid-1800s some companies still ignore it and choose to deploy secret proprietary encryption schemes which usually turn out to be insecure as soon as someone leaks the details of the algorithms.

The “Naive” RSA Algorithm on the difficulty of the RSA problem considered in Chapter 2, and hence it is based on the difficulty of finding the prime factors of large integers. However, we have seen that it may be possible to solve the RSA problem without factoring, hence the RSA algorithm is not based completely on the difficulty of factoring.

The Enigma Machineas an ideal solution. This idea had actually been used previously in a number of manual ciphers, but mechanization was able to make it far more efficient. The rotors could be implemented using wires and then encryption could be done mechanically using an electrical circuit.
