Enhance the Probability of Detection of Cooperative Spectrum Sensing in Cognitive Radio Networks Using Blockchain Technology

Algorithm 3

MU identification using digital signature verification.

(1)	Input: After energy detection, sets of results and are received as input. Now, the results are validated using the public key and private key components of digital signatures.
(2)	Valid User and MU as Output
(3)	for the to n choice,
(4)	if public key is validated
(5)	if the private key is confirmed.
(6)	Valid User is discovered
(7)	else
(8)	MU is found
(9)	end if
(10)	end if
(11)	end for
