WebJul 18, 2024 · A function which is one-to-one and which can be computed in a reasonable amount of time on a standard (classical) computer but whose inverse cannot feasibly be computed is called a [ cryptographic] one-way function. Multiplying two numbers, even very large numbers, can be done quite quickly on a computer. WebCiphertext indistinguishability is a property of many encryption schemes. Intuitively, if a cryptosystem possesses the property of indistinguishability, then an adversary will be unable to distinguish pairs of ciphertexts based on the message they encrypt. The property of indistinguishability under chosen plaintext attack is considered a basic requirement for …

WebA public-key cryptosystem is one in which messages encrypted with one key can only be decrypted with a second key, and vice versa. A strong public-key system is one in which possession of both the algorithm and the one key gives no useful information about the other key and thus no clues as to how to decrypt the message. WebSep 23, 2024 · DBTRU was proposed by Thang and Binh in 2015. As a variant of NTRU, the integer polynomial ring is replaced by two binary truncated polynomial rings GF(2)[x]/(xn+1). DBTRU has some advantages over NTRU in terms of security and performance.
