Can Homomorphic Cryptography ensure Privacy

摘要: The advent of information technology, the dramatic increase computational and storage capacities along with development worldwide communications promise very personalized, well designed convenient services. However, although privacy is an important right in our societies, these services often neglect abuse their consumers' privacy, by collecting sensible data notably. This work focuses on protection systems. For this, it known that traditional cryptography (e.g. encryption or signature schemes) necessary, for instance to ensure confidentiality, but not sufficient. To enable usability at same time, stronger tools are required. Homomorphic a possible promising candidate this purpose. technology allows manipulating encrypted performing logical operations without actually accessing clear. In particular, homomorphic envisioned as perfect secure computation (or storage) delegation cloud. investigates how can first giving deep insight field computer science (systems interest, tools, main goals, ...) then presenting more specifically (fully) encryption, aggregating done branch last 30 years. At last, gives clues answer question privacy?, interesting leads currently investigated yet be considered.
