the correct answer is * * 3 : rijndael * *. i arrived at this by recognizing that aes ( advanced encryption standard ) is based on the rijndael cipher, which was selected by nist after a competition. students may confuse this with other ciphers like blowfish or rc5, which are also well - known but unrelated to aes. to ... | M1 preference data |
to determine which assertion about \ ( r ^ \ star \ ) is false, let's analyze each statement step by step. 1. * * " a group. " * * the set of invertible elements in a ring \ ( r \ ), which we denote by \ ( r ^ \ star \ ), is indeed a group under the operation of multiplication. this is because : - * * closure : * * if ... | M1 preference data |
( - 1 \ ) ; thus, \ ( \ mathbb { z } - \ { 0 \ } = \ { \ ldots, - 2, - 1, 1, 2, \ ldots \ } \ ) contains many elements that are not invertible. therefore, \ ( r ^ \ star \ ) is a proper subset of \ ( r - \ { 0 \ } \ ) in most rings. 4. * * " the set of units. " * * this statement is also true since " units " is a term ... | M1 preference data |
