Abstract
A method for storing data in a cloud includes providing at least one data file to be stored together with a predefined number t of replicas of the at least one data file within the cloud, at least one authentication tag corresponding to the at least one data file and t functions that are configurable to take at least a predefined time to compute. The at least one data file, the at least one authentication tag and the t functions are transmitted to the cloud. The at least one data file is stored within the cloud and t solutions of the t functions are computed within the cloud. The t replicas of the at least one data file are generated based on the t solutions of the t functions and the at least one data file within the cloud. The t replicas are stored within the cloud.
