Abstract

In the secret sharing scheme, the reconstruction secret must to exposed to participants. In order to enforce the same secret sharing schemes, a new secret have to regenerate and redistribute for participants. Such a regeneration process is inefficient because of the overhead in the regeneration. In this paper, we proposed efficient secret regeneration scheme by eigenvalue. it can be also redistribution without revealing with other participants.

비밀분산방식에서, 재구성된 비밀은 참가자에게 노출된다. 동일한 비밀분산 방식을 유지하기 위해서, 새로운 비밀을 생성하고 참가자에게 재분배하여야 한다. 그러한 재생성과정은 비효율적이다. 본 논문은 참가자에게 노출되지 않고 고유치에 의해 효율적인 비밀 재생성과 재분배할 수 있는 방식을 제안한다.
