Based on the homogeneous linear recursive equation and the Elliptic curve cryptography (ECC), a fully dynamic secret sharing scheme is proposed for the general access structure of the participants. The participants choose their own … WebAbstract—Dynamic-committee proactive secret sharing (DPSS) enables the update of secret shares and the alternation of share-holders without changing the secret. Such a proactivization functionality makes DPSS a promising technology for long-term key management and committee governance. Although non-asynchronous DPSS schemes …
Web111 reconstruct Merent secrets (in different time instants) simply by sending to all participants the same broadcast message. Ham, Hwang, La&, and Lee [8] gave an algorithm to set up threshold secret sharing schemes (ie., characterized by an access structure consisting of aU subsets of participants of cardinality not 1- than some integer k), in … WebMay 1, 2024 · A ( t , n) threshold secret sharing scheme consists two phases. In the dealing phase, a dealer divides the secret into n shares and sends these shares to shareholders through secure channels. In the reconstruction phase, t or more than t shareholders can recover the secret by exchanging their shares.
