Web18 de out. de 2024 · Moreover, similar to Wang et al.’s idea, using the commutativity of products of circulant matrices, Santoso proposed an ElGamal-like BIPC encryption … WebThe Cramer–Shoup system is an asymmetric key encryption algorithm, and was the first efficient scheme proven to be secure against adaptive chosen ciphertext attack using standard cryptographic assumptions. Its security is based on the computational intractability (widely assumed, but not proved) of the decisional Diffie–Hellman assumption. simonswerk c1-15
