Nettet22. nov. 2024 · Shamir’s Secret Sharing, and its implementation in sss Shamir’s Secret Sharing scheme is a secret sharing scheme. The goal is to share a secret between n participants, and require at least k participants to retrieve it. SSS implements this using polynomials. This is best described by the Wikipedia’s article on the matter: Nettet15. nov. 2010 · In some areas of cryptography, for example, authentication codes, binary linear codes are not interesting because Concluding remarks Based on a class of binary irreducible cyclic codes, a class of BCH codes, the double-error correcting BCH codes and Melas codes, we presented secret sharing schemes, respectively.
