Paillier's cryptosystem revisited
Web2.1 Paillier’s cryptosystem Paillier’s public-key cryptosystem [Pai99] uses an RSA modulus N= pqwhere the secret compo-nents pand qare large primes with equal bit length. In fact, it must hold that gcd(pq;(p 1)(q 1)) = 1, which is easily satis ed if pand qare of equal bit length. The public key is (N;g), where g2Z N2 WebApr 20, 2024 · 2 Answers. This can be done by using a zero-knowledge proof to prove that a Paillier ciphertext is an encryption of zero. Specifically, let c be the original ciphertext, and …

Private set intersection (PSI) is where two parties each have a set and one or both parties discover (s) the intersection between them without revealing the other elements in their respective sets. A salient example would be for a COVID-19 contact tracing app. Suppose a public health authority holds—in a centralised ...
