XOR-based visual cryptographic schemes for non-monotonic (k, n)-threshold access structures deviate from the fact that the superset of any collection of k+1 or more participants may not get the secret back while providing their shares together. In this paper, we generalize this access structure...
XORORSecurity of secret sharing schemes has become a significant issue as secret communication is now being widely used. Random grid based visual secret sharing (RG-VSS) schemes has drawn greater attentiondoi:10.1007/978-981-10-0251-9_37
the re-sharing comprising: computing at least one first shared share, wherein the first shared share defines both the first value and the second value based on third shares defining the first value and fourth shares defining the second value; computing at least one second share defining the fir...
⊕XORReturnstrueif the operands are different ⊽NORReturnstrueif all operands are false. ⊼NANDReturnsfalseonly if both values of its two inputs are true. Number Systems Number systems are mathematical systems for expressing numbers. A number system consists of a set of symbols that are used...
After that, many kinds of QSS schemes have been proposed. For example, Liu et al. [4] presented the multiparty QSS using symmetric W state, which can use only a single photon measurement and XOR operation to recover the secret. Han et al. [5] illustrated an improved QSS scheme with ...

Some studies on the secret-image sharing problem have not been based on VC. Most of these schemes can recover high-quality images but require complicated cryptographic computations. Liu et al. used three Boolean operations, bit-level XOR, COV(1, 7, 3) from (7, 4), a Hamming code, and...
It is no secret that we are quite enamored with most of the LEGO games thatTraveller’s Taleshas put out. We own almost the whole set, and have played them all. Our current household ranking of the games, from most to least favorite, is: ...
A lock and key share (2, m, n) scheme generates m lock and n key shares, and retrieval of original secret is possible if and only if one share is selected from the set of m lock shares and other from the set of n key shares. Both OR-based and XOR-based decryptions are ...
