Abstract
A method (10) for generating operating entropy is provided. The method (10) is performed by a cloud computing entity (2) run on shared underlying resources (3). The method (10) comprises: sending (11) a respective entropy request to one or more servers (5a, 5b, 5c), inserting in each entropy request a respective timestamp, receiving (12) a response from each of the one or more servers (5a, 5b, 5c), each response payload comprising random bytes of unknown amount of entropy, verifying (13) validity of each response by comparing the respective timestamp in each response to a corresponding stored timestamp, and generating (14) the operating entropy based on at least one of the received responses. A cloud computing entity (2), a computer program and a computer program product are also provided.
