Optimal multiple assignments based on integer programming in secret sharing schemes with general access structures
Mitsugu Iwamoto, Hirosuke Yamamoto, Hirohisa Ogawa
It is known that for any general access structure, a secret sharing scheme (SSS) can be constructed from an (m,m)-threshold scheme by using the so-called cumulative map or from a (…

Quantum Secret Sharing Schemes and Reversibility of Quantum Operations
Tomohiro Ogawa, Akira Sasaki, Mitsugu Iwamoto +1
Quantum secret sharing schemes encrypting a quantum state into a multipartite entangled state are treated. The lower bound on the dimension of each share given by Gottesman [Phys.…
