Abstract
According to an embodiment of a first aspect of the invention, there is provided a distributed network comprising a plurality of subnets. Each of the plurality of subnets comprises a changeable set of nodes. The network is configured to generate for each of the plurality of subnets, by a distributed key generation protocol, an individual static verification key of a public-key signature scheme and a first set of corresponding secret key shares for a first set of nodes of the respective subnet. The network is further configured to redistribute, for each of the plurality of subnets, by a secret-redistribution protocol, the secret key shares of the respective first set of secret key shares to a second set of nodes of the respective subnet, thereby creating a second set of secret key shares corresponding to the same static verification key of the respective subnet.Further aspects of the invention relate to a corresponding computer-implemented method, a node, a computer program product and a software architecture.
