Abstract
Emerging applications based on the IoT are introducing new security challenges. They operate in a dynamic environment dominated by the evolution of the security threats and the variation of network features (e.g., network topology, energy level). One of the major challenges that should be tackled is the trade-off between robustness and energy-efficiency. This strengthens the need for in-network processing such as aggregation and compression to limit the computational, memory, and storage overhead. Existing cryptographic algorithms and protocols are not compliant with such processing and turn out to affect the lifetime the mobile nodes being part of the IoT. To cope with this problem, homomorphic encryption is introduced in this talk as an alternative to improve the applicability cryptographic solutions to IoT-based applications. Concrete examples are described and analyzed in order to illustrate the potential brought by homomorphic encryption in providing energy-effective protection of the IoT.
