Depending on the backend, AEAD modes can be used with different key sizes: 128 bits, 192 bits, and 256 bits. Key size is set by selecting a proper information object. /* selecting information object for CCM mode to use a 128-bit key */

CCM mode is a mode of operation for cryptographic block ciphers. It is an authenticated encryption algorithm designed to provide both authentication and confidentiality. CCM mode is only defined for block ciphers with a block length of 128 bits. The nonce of CCM must be carefully chosen to never be used more than once for a given key. This is because CCM is a derivation of CTR mode and the latter is effectively a stream cipher.

We design a lightweight blockcipher-based AEAD mode of operation called SAEB: the ﬁrst mode of operation that satisﬁes all the ﬁve properties to the best of our knowl-edge. Performance of SAEB is evaluated in various software and hardware platforms. The evaluation results show that SAEB outperforms conventional blockcipher-based

The design is based on Tweakable Block Ciphers (TBC). Specifcally, it can be seen as a slight adaptation of the Romulus-N [IKMP20a, IKMP20b] AEAD mode, following the same design philosophy, but introducing new ideas and design strategies to achieve leakage resilience.

Recently, new modes of operations (AEAD, for Authenticated Encryption with Associated Data) have been designed to combine encryption and authentication into a single, efficient primitive. Optionally, some part of the message can also be left in the clear (non-confidential associated data , such as headers), while the whole message remains fully authenticated.

Therefore, there is a great demand for lightweight mode of operation, especially that for authenticated encryption with associated data (AEAD). Among many known properties of conventional modes of operation, the following four properties are essential for constrained devices: 1. AES Galois/Counter Mode (AES-GCM) is a family of AEAD algorithms based upon AES. This specification makes use of the AES versions that use 128-bit and 256-bit keys, which we call "AES-128" and "AES-256", respectively. Any AEAD algorithm provides an intrinsic authentication tag. Blockcipher-based AEAD: ⚫internal state, plain/ciphertext block -> RAM/resister. ⚫blockcipher, mode of operation -> program/circuit.

An AEAD (authenticated encryption with additional data) mode is a type of block cipher mode that simultaneously encrypts the message as well as authenticating it. Additional unencrypted data may also be authenticated.

encrypt (nonce, 'authentication data', 'plaintext') plaintext = cipher. decrypt (nonce, 'authentication data', aead) Note that GMAC within GCM also performs multiplication over 128 bit blocks. The online property is therefore considered for the cipher part of the AEAD mode only. Conclusion: CCM has not been defined to offer online encryption / decryption, and there are serious issues with using AEAD ciphers for online encryption / decryption even if it was.
