A New Multistage Encryption Scheme Using Linear Feedback Register and Chaos-Based Quantum Map

Algorithm 1

Algorithm of Linear Feedback Shift Register.

	Input: key
	Output: pseudorandom numbers sequence
(1)while value! = 0 and value is not reiterating,
	Do
(2)Bin ⟵ attain the binary configuration of the Value.
(3)Pad until bin has 16 bits with leading zeros.
(4)XOR the bits at situations respective to LF function and save it in m.
(5)Bin ← shift the bin by one toward the right.
(6)Pad until bin has 16 bits with leading zeros.
(7)The first bit is replaced with m in the bin.
(8)Value ← attain the decimal value of the obtained binary configuration.
(9)	End
