Cryptographic computations
Webcryptography. For this reason, I have chosen this topic in order to broaden and deepen my understanding of present-day cryptography. Quantum computation relies heavily on linear algebra, physics, and some com-plexity theory, and while I have taken Linear Algebra, Physics, Algorithms, and Theory of Computation, I

The message you wish to send is converted to a cipher text that appears to be gibberish unless you know the secret to unlocking it.
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… WebWe identify a broad class of multi-party cryptographic computation problem, including problems subject to the partial-information constraints of the "mental games" of Goldreich, Micali, and Wigderson [24]. In order to solve any cryptographic computation problem, we develop new techniques that can be implemented efficiently in the public-key model.
