"Web2.1.1 Attack Models. The same attack models apply here. Although an encryption function is automatically given to each principal, nothing immediately guarantees that adversaries have access to a decryption function. As before, Chosen Ciphertext Attack (CCA) and Chosen Ciphertext Attack 2 (CCA2) apply, and CCA2 implies Non-Malleability, as before. " - Cryptographic attack models

Some common attack models are: Ciphertext-only attack (COA) - in this type of attack it is assumed that the cryptanalyst has access only to the ciphertext, and has no access to the plaintext. This type of attack is the most likely case encountered in real life cryptanalysis, but is the weakest attack because of the … See more In cryptanalysis, attack models or attack types are a classification of cryptographic attacks specifying the kind of access a cryptanalyst has to a system under attack when attempting to "break" an encrypted message (also … See more • Niels Ferguson; Bruce Schneier (2003).

Entropy is critically important to the model-building resistance of the PUF.

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. Webrecent innovative attack (ADD REFERENCES)) that completely side-step the adversarial model and as expected completely breaks the security of the scheme. However, this only serves as motivation to model stronger adversaries and thereby construct more robust cryptosystems that are provably robust (with respect to the new models).
