WebMar 5, 2016 · As cryptography is a mathematical science, one needs a (mathematical) definition of computation and of the complexity of computation. In modern cryptography, and more generally in theoretical computer science, the complexity of a problem is defined via the number of steps it takes for the best program on a universal Turing machine to … A cryptosystem that supports arbitrary computation on ciphertexts is known as fully homomorphic encryption (FHE). Such a scheme enables the construction of programs for any desirable functionality, which can be run on encrypted inputs to produce an encryption of the result. Since such a program need never decrypt its inputs, it can be run by an untrusted party without revealing its inputs and internal state. Fully homomorphic cryptosystems have great pra…
