WebApr 16, 2024 · We answer this question in the affirmative, and show that we can allow arbitrarily large gaps between m and n, up to exponential \(m = 2^{O(n)}\).Surprisingly, this shows that unlike time-bounded public-key cryptography,—where we must rely on additional computational assumptions,—space-bounded public-key cryptography can be proven … 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…
