| Abstract(in English) | In Shamir's (k,n)-threshold secret sharing scheme, a heavy computational cost is required to recover the secret from k shares. As a solution to this problem, several fast threshold schemes are proposed. However, there is no fast ideal (k,n)-threshold scheme, where k >_ 4 and n is arbitrary. This paper proposes a new fast (4,n)-threshold scheme using just EXCLUSIVE-OR(XOR) operations to make shares and recover the secret, which is an ideal secret sharing scheme similar to Shamir's scheme. Furthermore, we extend and generalize the (4,n)-threshold scheme to a new fast (k,n)-threshold scheme using XOR operations with arbitrary k and n, which is also an ideal secret sharing scheme. |
