- Block cipher : A symmetric cipher that operates on fixed-size blocks of plaintext, giving a block of ciphertext for each
- Code book attack : Attacking a block cipher by creating a code book, collecting plaintext/ciphertext pairs.
- Cryptography : A field at the intersection of mathematics and computer science that is concerned with the security of information, typically the confidentiality, integrity and authenticity of some message.
- Hashed message authentication code : A technique for authenticating a message using a hash function and a secret key.
- IPsec : Internet Protocl security is a set of protocols for providing encryption and/or authentication services for Internet packets.
- Stream cipher : A cipher that encrypts data by mixing it with the output of a pseudorandom number generator controlled by a key; to decrypt, run the same generator with the same key to get the same pseudorandom data, then reverse the mixing step.
- Symmetric key cryptography : A cryptographic system in which there is only one key; the same secret key is used for encryption and decryption.
