Abstract
The long-standing problem of secure communication is to distribute/generate unbreakable key over a communication channel. Classically the problem is believed to be unsolvable. For secure communication and authentication we are dependent on computationally secure cipher systems. Over the last two decades quantum key distribution systems have been developed to solve the problem, but the problem is yet to be solved in practical settings. The invented classical key distribution/generation system solves the problem.
Claims13
A Communication system comprising:
- at least one sending unit and at least one receiving unit connected to a communication channel,
- sharing a secret key for the purpose of generating new keys over the said communication channel by re-using the sub keys,
- where key is a sequence of random numbers and sub key is a sequence of random positions of random number.
The communication system comprising:
- at least two receiving units, each connected to one sending unit by communication channel where the said two receiving units sharing a secret key for the purpose of generating new keys over the two said communication channels by re-using the sub keys,
- where key is a sequence of random numbers and sub key is a sequence of random positions of random number, and
- the said sending unit is not aware of the said secret key and its sub keys.
