Hash functions are extremely useful and appear in almost all information security applications. A hash function is a mathematical function that converts a numerical input value into another compressed numerical value. The input to the hash function is of arbitrary length but output is always of fixed length. cs source lan serverWebFully homomorphic encryption (FHE) has been called the \Swiss Army knife of cryptog-raphy", since it provides a single tool that can be uniformly applied to many cryptographic applications. In this tutorial we study FHE and describe its di erent properties, relations with other concepts in cryptography, and constructions.
