Block ciphers encrypt one block of plaintext bits at a time, to a block of ciphertext bits, through multiple rounds, and using a secret key. Each round is a sequence of several simple transformations, which provide confusion and diffusion [522]. In each round, a round key is used, which is derived from the secret key using a key schedule algorithm....
Stream ciphers encrypt small portions of data (one or several bits) at a time. By using a secret key, they generate a pseudorandom keystream, which is then combined with the plaintext bits to produce the ciphertext bits. Very often the combining function is bitwise XORing, and in that case we speak about binary additive stream ciphers. The basic se...
A hash function is any function that maps a variable length input message into a fixed length output. The output is usually called a hashcode, message digest, hash value or hash result. Cryptographic hash functions must be preimage (one-way), second preimage and collision resistant. Usually the message is first padded and then divided into blocks o...
A message authentication code (MAC) protects the integrity and authenticity of a given message, by generating a tag from the message and a secret key. MAC schemes can be constructed from block ciphers (e.g., CBC-MAC (part of the ISO/IEC 9797-1:1999 standard) or OCB-MAC [504]), from cryptographic hash functions (e.g., HMAC (RFC 2104)), etc. Three li...
Authenticated encryption (AE) schemes combine the functions of ciphers and MACs in one primitive, so they provide confidentiality, integrity, and authentication of a given message. Besides the plaintext and the secret key, they usually accept variable length Associated Data (AEAD schemes), a public nonce, and an optional secret nonce. AD is a part ...

There are, in general, three types of cryptographic schemes typically used to accomplish these goals: secret key (or symmetric) cryptography, public-key (or asymmetric) cryptography, and hash functions, each of which is described below. In all cases, the initial unencrypted data is referred to as plaintext.
Feb 18, 2024 · This situation requires creating a “lightweight” type of cryptographic algorithm for these devices. This article analyzes existing lightweight cryptographic algorithms based on various factors: security, energy consumption, and hardware and software implementation.
