With myriads of small and pervasive devices in the authors' digital age, the availability of low-power and energy-efficient processing technology has become absolutely essential. Most of these constrained devices need to incorporate security services for confidentiality and privacy in addition to their primary tasks - typically involving computationally expensive cryptography. In the last years, many researchers have worked on novel lightweight cryptographic constructions to minimize the computational burden on the constrained devices. However, most of those alternative constructions sacrificed security for simplicity, potentially enabling just as simple attacks.
