When securing the outsourcing of sensor data to the cloud, the representation of the sensor data and the choice of security measures applied to it are key. This paper presents the SensorCloud protocol, which enables the representation of sensor data and actuator commands using JSON, as well as the encoding of the object security mechanisms applied to a given sensor data item. It utilizes mechanisms that have been or currently are in the process of being standardized at the IETF to aid its wide applicability.

Much commercial cryptography uses the mathematical functions of discrete logarithms (example?). The security of these algorithms rests on the assumption that the mathematical functions are impossible to solve. Recently, this assumption has come under strain. First a researcher solved the first of three parts of the ‘puzzle’ that could lead to the solution of discrete logarithms. The next two phases have also been attacked and simplified for certain special case of discrete logarithm. Existing applications are still considered strong however the researchers used this progress to attack a family of discrete logarithm algorithms proposed for the next generation of internet encryption. The simplifications they could derive meant that the decryption problem could be processed in just 2 hours, effectively rendering the new algorithm broken. The clear lesson is banking on the long term security of specific algorithms is increasingly uncertain.
