A New Self-Updating Hash Chain Structure Scheme

Self-Updating Hash Chain can be used extensively in many fields, such as one time password (OTP), signatures and authentication etc. In this paper, we propose a new self-updating hash chain based linear partition-combination algorithm (LPCA), which can share data into m parts and any part can' t leak any information of data s. At a each exchange process, one part of s is transferred. When servers receive k(k
