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… WebJul 4, 2007 · 1. Cryptography.- 1. Early History.; 2. The Idea of Public Key Cryptography.; 3. The RSA Cryptosystem.; 4.
