Question 4 15 pts Answer the following to find the multiplicative inverse of 12 in GF(23) domain using Fermat's little theorem. p= [ Select ] a= [ Select ] and= ap-2 mod [ Select ] = 1221 mod [ Select ] = 12*(144) [ Select ] mod 23 = 12*610 mod 23 = 12*(36) [ Select ] mod 23 =12*135 mod 23 = 12*4 mod 23 [ Select ] mod 23 So inverse of 12 in GF(23) domain = [ Select ] Verification: 12* [ Select ] mod 23 = 1
