Tightly coupled multi-group threshold secret sharing based on Chinese Remainder Theorem

(t,n)-Threshold secret sharing ((t,n)-SS) scheme is a fundamental cryptographic primitive. As a special (t,n)-SS, a Multi-Level threshold Secret Sharing scheme (MLSS) divides shares into different levels. Shares at higher levels can be used at lower ones but shares of lower levels are invalid at hig...
