Abstract
According to a first aspect of the present invention there is provided a method of at least partly delegating processing of data in a machine-to-machine system to reduce computational load on a broker entitywhile maintaining security of the data to be processed, the broker entityserving as a link between a nodeof a sensor network providing the data and an application noderequesting the data. In the method, at the broker entity, following receipt of a request for processed data from the application node, determining the node to provide the data to be processed, generating a data key for the data-providing node, generating a data-processing algorithm for processing the data in dependence upon the request, sending the data key to the data-providing node, and sending the data key and data-processing algorithm to a remote data-processing entity. At the data-providing node, encrypting the data using the data key and sending the encrypted data to the data-processing entity. At the data-processing entity, decrypting the data using the data key, processing the data using the data-processing algorithm, and sending the processed data to the application node
