In the last years, a number of research sensor nodes based on combination low-power microcontrollers and FPGAs have been proposed. these platforms, serve as accelerators complex algorithms, making it possible to process vast amount sensing data in real time. medical applications that rely sensors, both privacy security are utmost importance. However, execution cryptographic primitives solely upon clocked at low frequency can affect overall power consumption platform. this manuscript, we...

Measuring efficiency is difficult. In the last decades, several works have contributed in quest to successfully determine and compare of pairing-based attribute-based encryption (ABE) schemes. However, many these are limited: they use little no optimizations, or underlying pairingfriendly elliptic curves that do not provide sufficient security anymore. Hence, using benchmark ABE schemes does yield accurate results. Furthermore, most design papers focus on one important aspect. For instance,...

Typically, commercial sensor nodes are equipped with MCUsclocked at a low-frequency (i.e., within the 4-12 MHz range). Consequently, executing cryptographic algorithms in those MCUs generally requires huge amount of time. In this respect, required energy consumption can be higher than using separate accelerator based on Field-programmable Gate Array (FPGA) that is switched when needed. manuscript, we present design suitable for an FPGA-based node and compliant IEEE802.15.4 standard. All...

Attribute-based encryption (ABE) is a popular type of public-key that enforces access control cryptographically, and has spurred the proposal many use cases. To satisfy requirements setting, tailor-made schemes are often introduced. However, designing secure schemes---as well as verifying they secure---is notoriously hard. Several these have turned out to be broken, making them dangerous deploy in practice.
