Security Analysis of HMAC/NMAC by Using Fault Injection [PDF]
Journal of Applied Mathematics, 2013 In Choukri and Tunstall (2005), the authors showed that if they decreased the number of rounds in AES by injecting faults, it is possible to recover the secret key.

Soft Analytical Side-Channel Attacks on SHA-2 and HMAC
Transactions on Cryptographic Hardware and Embedded SystemsWe investigate the use of bit-level Soft Analytical Side-Channel Attacks (SASCA) to recover secret inputs of the SHA-256 hash function, and secret keys of HMAC-SHA-256, using Sentential Decision Diagrams to overcome the computational challenge posed to ...

Deep Learning-based Side Channel Attack on HMAC SM3. [PDF]
International Journal of Interactive Multimedia and Artificial Intelligence, 2020 SM3 is a Chinese hash standard. HMAC SM3 uses a secret key to encrypt the input text and gives an output as the HMAC of the input text. If the key is recovered, adversaries can easily forge a valid HMAC.

When Messages Are Keys: Is HMAC a Dual-PRF? [PDF]
, 2023 In Internet security protocols including TLS 1.3, KEMTLS, MLS and Noise, HMAC is being assumed to be a dual-PRF, meaning a PRF not only when keyed conventionally (through its first input), but also when swapped and keyed (unconventionally) through its ...

Generic Security of NMAC and HMAC with Input Whitening [PDF]
, 2015 HMAC and its variant NMAC are the most popular approaches to deriving a MAC and more generally, a PRF from a cryptographic hash function. Despite nearly two decades of research, their exact security still remains far from understood in many different contexts.

On Authentication with HMAC and Non-random Properties [PDF]
, 2007 MAC algorithms can provide cryptographically secure authentication services. One of the most popular algorithms in commercial applications is HMAC based on the hash functions MD5 or SHA-1. In the light of new collision search methods for members of the MD4 family including SHA-1, the security of HMAC based on these hash functions is reconsidered. We

Optimization of PBKDF2-HMAC-SHA256 and PBKDF2-HMAC-LSH256 in CPU Environments [PDF]
IEEE Access, 2020 Password-Based Key-Derivation Function 2 (PBKDF2) is commonly employed to derive secure keys from a password in real life such as file encryption and implementation of authentication systems. Nevertheless, owing to the limited entropy of the password, the security of the generated keys is lower than that of the normally generated keys. To address this,
