Adaptive Chosen Ciphertext Attack
Adaptive chosen ciphertext attack (ACCA) is a type of cyber attack in cryptography where the attacker makes use of a cipher’s decryption oracle to gain knowledge about the secret key. The attacker sends carefully crafted ciphertexts to the oracle until enough information is gained to compromise the system.
In simpler terms, ACCA is when someone tries to hack into an encrypted system by sending disguised messages to the decoder until they figure out how to decode the system’s secret key.
This type of attack can be particularly harmful because it is very difficult to detect and can potentially break even the strongest encryption systems. As a result, strong preventative measures and countermeasures are necessary to protect against ACCA attacks.
Overall, the best defense against ACCA attacks is to use strong encryption methods and be vigilant against any suspicious activity.
