The _________ attack exploits the common use of a modular exponentiation algorithm in RSA encryption and decryption, but can be adapted to work with any implementation that does not run in fixed time.
A) mathematical
B) timing
C) chosen ciphertext
D) brute-force

Question

Quizplus · Accepted Answer

The given attack is a timing attack, which exploits the implementation vulnerabilities in RSA encryption and decryption. Hence, option B is the correct answer. Option A is not a suitable choice because mathematical attacks generally refer to attacks that exploit mathematical weaknesses in the encryption algorithm. Option C is incorrect because the attack does not involve choosing the ciphertext, but rather manipulating the timing. Option D is incorrect because a brute-force attack involves trying all possible combinations of keys or passwords, which is not relevant to this given attack.
