!!! Overview
[{$pagename}] is a form of [encryption] that allows computations to be carried out on [ciphertext], which when applying [decryption], matches the result of operations performed on the [plaintext].
[{$pagename}] is a method used in [Privacy Enhancing Technologies]
[{$pagename}] is sometimes a desirable feature in modern communication system architectures.
[{$pagename}] can be used for privacy-preserving outsourced [DataStore] and [Cloud computing]. This allows data to be [encrypted] and out-sourced to commercial [Cloud computing] environments for processing, all while [encrypted]. For [example], predictive [Analytics] in [HealthCare] can be hard to apply due to medical [Data Privacy] concerns, but if the predictive analytics service provider can operate on [encrypted] [data] instead, these privacy concerns are diminished.
[{$pagename}] could allow the chaining together of different services without exposing the [data] to each of those services. For [example], a chain of different services from different companies could calculate
* the tax
* the currency exchange rate
* shipping
on a transaction without exposing the unencrypted data to each of those services.[1]
[{$pagename}] [algorithms] are malleable by design. This enables their use in cloud computing environment for ensuring the [confidentiality] of processed data. In addition the homomorphic property of various cryptosystems can be used to create many other secure systems, for example secure voting systems,[2] [collision Resistance] [Hash Functions], private information retrieval schemes, and many more.
There are several partially homomorphic crypto-systems, and also a number of fully homomorphic crypto-systems.
!! Why NOT being used?
The catch of using [{$pagename}] is, in its current state, is impractically slow, in part, because it has a larger computational overhead than [plaintext] and other [Encryption] operations.
