RASS — A concurrency based bitwise symmetric key cryptographic algorithm

The security and strength of any cryptosystem's encryption depend on the difficulty, both in terms of time and technique, of cracking the message. This paper suggests a bit cipher, a symmetric key cryptographic algorithm which provides bit-level security with linear time complexity and robust security (two 16 bit keys), and uses optimal time compared to other such ciphers by implementing concurrency through multithreading.
