In order to make a cipher more difficult to break, one could use various keys in cryptosystem. This would help to cover any perceptible patterns in the ciphertext. In fact, one can produce unbreakable ciphertext by supplying randomly generated key on each bit of data that is mathematically infeasible to break. Since different random bits or keys would not lead to any repeating patterns. For the first time, in this paper, we present a construction method to generate multiple random keys from a core-key with highest possible immunity to crack. We are with a particular emphasis on novel technique to secure user data, we have designed a secure and cost effective new cryptosystem called Rbits (Random bits) cipher. In different directions we identify that Rbits having highest immunity to crack and presenting various analysis tests in support from this viewpoint.}, }
