Keywords: ramp secret sharing, multiplicative secret sharing, strong security, algebraic geometry code


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.
