Forgotten Secret Recovering Scheme and Fuzzy Vault Scheme Constructed Based on Systematic Error-Correcting Codes

Masao KASAHARA

Abstract: In this paper, we revisit the Forgotten Secret Recovering Scheme for $k$ users, referred to as FSRS($k$) previously proposed by the present author. FSRS($k$) takes advantage of the fact that Reed-Solomon code used in FSRS($k$) is constructed in a form of systematic code. We show that a particular class of FSRS($k$), FSRS($1$), can be successfully applied to the various cryptoscheme including Fuzzy Vault Scheme (FVS).
