Traceable Secret Sharing Based on the Chinese Remainder Theorem

ePrint Report: Traceable Secret Sharing Based on the Chinese Remainder Theorem

Charlotte Hoffmann

Traceable threshold secret sharing schemes, introduced by Goyal, Song and Srinivasan (CRYPTO'21), allow to provably trace leaked shares to the parties that leaked them. The authors give the first definition and construction of traceable secret sharing schemes. However, the size of the shares in their construction are quadratic in the size of the secret.
