Encrypting homomorphisms
Cryptographic homomorphisms are used to charge a company with performing calculations where both input and output data are confident and therefore can be communicated in cryptographic ways only. This requires the use of special cryptography so that operations can be performed on coded data and decoding the results one gets the same result as if the calculation were made with uncoded data. This is the main point of the article which also introduces basic methods and possible attacks.
