WebJun 7, 2024 · Authentication, in particular, requires the PUF to produce a very large number of challenge-response-pairs (CRPs) and, of even greater importance, requires the PUF to be resistant to adversarial attacks that attempt to model and clone the PUF (model-building attacks). Entropy is critically important to the model-building resistance of the PUF. WebDeep Neural Network (DNN) models have been extensively developed by companies for a wide range of applications.

WebFrom the 'Cryptographic attacks' models taught in Block 2, Part 4 (Week 9), you may have learnt that the core objective of all cryptographic attacks is to retrieve the keys used in encrypting a given piece of data or information. A chosen-plaintext attack (CPA) is an attack model for cryptanalysis which presumes that the attacker can obtain the ciphertexts for arbitrary plaintexts. The goal of the attack is to gain information that reduces the security of the encryption scheme. Modern ciphers aim to provide semantic security, also known as ciphertext indistinguishability under chosen-plaintext attack, and they are therefore, by design, generally immune to chosen-pla…
