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 … WebIn cryptography, security level is a measure of the strength that a cryptographic primitive — such as a cipher or hash function — achieves.

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.
