What are bitwise operations and how are they used in security?

Bitwise operations are operations that directly manipulate bits of binary numbers. In security, they are often used for tasks like encryption, hashing, and data masking.

Can you give me an example of a bitwise operation in a security context?

Sure! A common example is using the XOR operation for encryption. By XORing plaintext with a key, you can create ciphertext that is difficult to decipher without the key.

How does XOR encryption compare to other encryption methods?

XOR encryption is simple and fast, but it's not very secure on its own. It's often used in combination with other methods to enhance security.

What are some common vulnerabilities associated with bitwise operations?

Common vulnerabilities include bit flipping attacks, where an attacker changes specific bits to manipulate data, and improper handling of bitwise operations that can lead to security flaws.
