I believe that the correct answer will be C. Adaptive chosen-plaintext attack . Please check.

The correct answer is: C. Adaptive chosen-plaintext attack Explanation: In an Adaptive chosen-plaintext attack (ACPA), the attacker makes a series of interactive queries, where subsequent plaintexts are chosen based on the information from previous encryptions. This allows the attacker to adapt their strategy based on previous results, which can provide deeper insights into the encryption system's workings.

The attack method described, where the attacker makes a series of interactive queries and chooses subsequent plaintexts based on the information from the previous encryptions, is option C: Adaptive chosen-plaintext attack. In an adaptive chosen-plaintext attack, the attacker has the ability to choose plaintexts and obtain their corresponding ciphertexts, and based on the information gained from these queries, the attacker adapts their choice of subsequent plaintexts. The goal is to exploit any patterns or weaknesses in the encryption algorithm or system to gain additional information or break the encryption.

should be C

Adaptive chosen-plaintext attack

it's definitely C

Its literally definition of C. Adaptive chosen-plaintext attack

%100 Adaptive Chosen-plaintext Attack Adaptive Chosen-plaintext Attack: Attacker makes a series of interactive queries, choosing subsequent plaintexts based on the information from the previous encryptions

Adaptive chosen plain-text attack - attacker makes a series of interactive queries choosing subsequent plaintexts based on the information from the previous encryptions; idea is to glean more and more information about the full target cipher text and key. The answer should be C

All sources I have found show that C is correct but in my v10 exam A was correct.

I would say C. From Matt Walker all-in-one book: Adaptive chosen plain-text attack The EC-Council definition for this is mindnumbingly obtuse: “the attacker makes a series of interactive queries, choosing subsequent plaintexts based on the information from the previous encryptions.” What this really means is the attacker sends bunches of cipher texts to be decrypted and then uses the results of the decryptions to select different, closely related cipher texts. The idea is to gradually glean more and more information about the full target cipher text or about the key itself.

The answer should be C I think. https://simple.wikipedia.org/wiki/Chosen-plaintext_attack#:~:text=A%20chosen%2Dplaintext%20attack%20(CPA,security%20of%20the%20encryption%20scheme.

With chosen-plaintext attack, the attacker is allowed to choose an arbitary amount of plaintext to encrypt. ... With the adaptive-chosen-plaintext attack, he/she can do the same as with the Definetely C:chosen-plaintext attack, but is also allowed to encrypt new data after the attacker has looked and analyzed previous encrypted bits

Answer is C : Adaptive chosen-plaintext attack

There is an Apdative-ChoSEN attack and Adpative-choSE attack, there are subtle differences, the answer is C

Chosen-PlainText Attack:Attacker Defines his own plaintext, feed it into the cipher, adn analyzes the resulting cyphertext Ciphertext-only attack-Attack has access to the cipher text; goal of this attack is to recovery the encrypiton key from the cypher text AdaptiveChose Plaintext attack:Attacker makes a series of interactive queries, chosing subsequent text based infmraiton from the previous encryptions known-plaintext attack:attackers had knowedge of some part of the plain text; usign this informaiton, the kye used to generate ciphertext is deduced so as to decipher other messages

Adaptive chosen-plaintext is a function based in the chosen-plaintext so correct answer is A
