Block Cipher: A method of encrypting data where plaintext is divided into fixed-size blocks, typically 64 or 128 bits, which are then encrypted one block at a time using a specific key. Common block ciphers include AES (Advanced Encryption Standard) and DES (Data Encryption Standard). Block ciphers provide strong security by ensuring each block of data is encrypted independently, making unauthorized decryption more difficult.
