We propose a privacy-friendly smart metering architecture which is yet flexible enough to serve various future third party energy services. Our secure architecture may be deployed as a cloud service and allows processing of SQL queries on encrypted measurements, providing aggregated results in a most flexible manner. A combination of homomorphic encryption(More)
Available purely software based code attestation protocols for wireless sensor nodes have recently been shown to be cheatable. For instance, an attacker can gain free space within a node's program memory through a so called compression attack to subsequently inject a bogus code image, compromising the node. In this work we propose and implement a code(More)
