This article is to initiate the study of
evolving secret sharing sharing such that both share generation and reconstruction algorithms can be implemented by AC0 circuits. We give a concrete
construction with some minor storage assumption. Furthermore, we consider
the novel problem of robust redistribution of secret shares (in AC0) to realize
dynamic access structure by suitably modifying a construction of Chen-Ishai-
Li (TCC 2017).
