Abstract
Official abstract text for this publication.
There are provided a method, a system and an initiator server for a secure execution of workflow tasks of a workflow to be executed according to a given execution pattern in a distributed workflow management system within a decentralized network system with a plurality of servers (b 0 , b 1 , . . . , b n ) including at least an initiator server and at least a number of groups of servers of the plurality of servers. Each group satisfies a policy (pol i ) of a vertex, and thus, knows a corresponding policy key pair including a policy private key (SK poli ) and a policy public key (PK poli ), respectively. Each vertex denotes a set of workflow tasks to be executed in accord with the execution pattern and is assigned a vertex key pair including a vertex private key and a vertex public key. The vertex private keys and the policy public keys are jointly encrypted within a first onion structure, the first onion structure being built up of a number of onion layers representing the execution pattern which defines a succession of vertices such that each layer is decryptable by using the policy private key of exactly one vertex thus revealing the corresponding vertex private key.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for a secure execution of workflow tasks of a workflow to be executed according to an execution pattern in a distributed workflow management system within a decentralized network system with a plurality of servers (b 0 , b 1 , . . . , b n )including at least an initiator server and at least one or more groups of servers, the execution pattern being stateless such that, upon completion of required workflow tasks, each server sends all workflow d…
