Card-Based Overwriting Protocol for Equality Function and Applications

arXiv:2402.16290v1 Announce Type: new
Abstract: Research in the area of secure multi-party computation with an unconventional method of using a physical deck of playing cards began in 1989 when den Boar proposed a protocol to compute the logical AND function using five cards. Since then, the area has gained interest from many researchers and several card-based protocols to compute various functions have been developed. In this paper, we propose a card-based protocol called the overwriting protocol that can securely compute …
