Multilane HMAC— Security Beyond the Birthday Limit
Lecture Notes in Computer Science, 2007HMAC is a popular MAC (Message Authentication Code) that is based on a cryptographic hash function. HMAC is provided with a formal proof of security, in which it is proven to be a PRF (Pseudo-Random Function) under the condition that its underlying compression function is a PRF. Nonetheless, the security of HMAC is limited by a birthday attack, that is,

HSATA: Improved SATA Protocol with HMAC
2018 27th International Conference on Computer Communication and Networks (ICCCN), 2018The SATA (Serial Advanced Technology Attachment) is mainstream interface used in current computer systems. Research and improvement on its security is also becoming increasingly important. In order to enhance the authentication and integrity verification of traditional SATA protocol, HSATA, Improved SATA protocol with HMAC (Hash-based Message ...

Unintended Features of APIs: Cryptanalysis of Incremental HMAC
2021Many cryptographic APIs provide extra functionality that was not intended by the designers. In this paper we discuss such an unintended functionality in the API of HMAC, and study the security implications of it’s use by applications.

Generic Attacks on Strengthened HMAC: n-bit Secure HMAC Requires Key in All Blocks
2014HMAC is the most widely used hash based MAC scheme. Recently, several generic attacks have been presented against HMAC with a complexity between 2 n/2 and 2 n , where n is the output size of an underlying hash function. In this paper, we investigate the security of strengthened HMAC in which the key is used to process underlying compression functions ...

Differential Power Analysis of HMAC SHA-1 and HMAC SHA-2 in the Hamming Weight Model
2015As any algorithm manipulating secret data, HMAC is potentially vulnerable to side channel attacks. In 2004, Lemke et al. fully described a differential power attack on HMAC with RIPEMD-160 in the Hamming weight leakage model, and mentioned a possible extension to SHA-1. Later in 2007, McEvoy et al.

We present a new secret-prefix MAC (Message Authentication Code) based on hash functions. Just like the well-known HMAC algorithm, the new MAC can utilize current hash functions without modifying their Merkle-Damgard implementations. Indeed, the new MAC is almost the same as HMAC except that the second call to the secret key, which is made at the ...

Backdoored Hash Functions: Immunizing HMAC and HKDF
2018 IEEE 31st Computer Security Foundations Symposium (CSF), 2018Security of cryptographic schemes is traditionally measured as the inability of resource-constrained adversaries to violate a desired security goal. The security argument usually relies on a sound design of the underlying components. Arguably, one of the most devastating failures of this approach can be observed when considering adversaries such as ...

A HMAC-Based RFID Authentication Protocol
2010 2nd International Symposium on Information Engineering and Electronic Commerce, 2010Radio Frequency Identification (RFID) is a non-contact automatic identification technology, and has many applications, such as in logistics, transportation, retail, etc. The wireless communication channel of the RFID systems is vulnerable to various malicious attacks, and RFID tag has limited calculation resources and small storage capacity, aimed at ...

A Reconfigurable Hardware Unit for the HMAC Algorithm
2005 International Conference on Information and Communication Technology, 2006HMAC is a shared-key security algorithm that uses hash functions for message authentication and data integrity. The most popular hash functions used with HMAC are MD5, SHA-1, and RIPEMD-160, which are all based on the function MD4. IPSec uses HMAC with these three hash functions for message authentication.
