Known-Plaintext Attack (KPA) is a type of attack where an attacker has access to both the plaintext and its corresponding ciphertext. This allows the attacker to use this information to crack the encryption and gain access to sensitive data. The KPA works by analyzing the relationship between the plaintext and ciphertext.
By comparing the two, the attacker can identify patterns and weaknesses in the encryption algorithm. This can then be used to decrypt the ciphertext and reveal the plaintext. KPA is an effective attack when the attacker has access to multiple plaintext-ciphertext pairs. This is because it allows them to identify patterns and weaknesses in the encryption algorithm that may not be apparent from a single pair.
To protect against KPA, encryption algorithms should be designed to be resistant to this type of attack. This can be achieved by using strong encryption algorithms and ensuring that the encryption key is kept secure. Overall, KPA is a powerful attack that can be used to crack encryption and gain access to sensitive data.
However, by using strong encryption algorithms and keeping the encryption key secure, it is possible to protect against this type of attack.
