Privacy-enhancing cryptography-based materials

In this paper, we offer a comprehensible survey and classification on cryptographic schemes which serve as the building blocks for most privacy-enhancing protocols and systems being deployed nowadays. For each cryptography material here described we offer a brief description of its foundations, the privacy-related features it possesses and an illustration of its application to some real life scenarios. The classification proposed is, to the best of our knowledge, pioneer in collecting all cryptography material with regard to privacy.
