Symmetrically and Asymmetrically Hard Cryptography [PDF]
, 2017 The main efficiency metrics for a cryptographic primitive are its speed, its code size and its memory complexity. For a variety of reasons, many algorithms have been proposed that, instead of optimizing, try to increase one of these hardness forms.We present for the first time a unified framework for describing the hardness of a primitive along any of ...

Cryptographic Energy Costs are Assumable in Ad Hoc Networks [PDF]
, 2009 Performance of symmetric and asymmetric cryptography algorithms in small devices is presented. Both temporal and energy costs are measured and compared with the basic functional costs of a device. We demonstrate that cryptographic power costs are not
