Posted: 30 Nov 2018 10:11 AM PST confused about differences between 5 out of 5 threshold secret sharing scheme and 4 out of 5 threshold secret sharing scheme. how would the share and reconstruction schemes be different? For 5 out of 5 scheme: Sharing (m): s1:0,1}^l s2= s1 xor m1 .....until s10 return(s1...s10) Reconstruction (s1...s10): s1 xor ...s10 how would it be done for 4 out of 5 threshold sharing scheme ? do we just now only have sharing and reconstruction until s8 block?
