Strong Security of the Strongly Multiplicative Ramp Secret Sharing based on Algebraic Curves

Ryutaroh Matsumoto

Abstract: We introduce a coding theoretic criterion for Yamamoto's strong security of the ramp secret sharing scheme. After that, by using it, we show the strong security of the strongly multiplicative ramp secret sharing proposed by Chen et al. in 2008.
