Differential Power Analysis of HMAC Based on SHA-2, and Countermeasures [PDF]

open access: yes, 2007
The HMAC algorithm is widely used to provide authentication and message integrity to digital communications. However, if the HMAC algorithm is implemented in embedded hardware, it is vulnerable to side-channel attacks. In this paper, we describe a DPA attack strategy for the HMAC algorithm, based on the SHA-2 hash function family.

Exploring the SHA-2 Design Space. [PDF]

open access: yes, 2020
While SHA-2 is a ubiquitous cryptographic hashing primitive, its role in emerging application domains, such as blockchains or trusted IoT components, has made the acceleration of SHA-2 very challenging due to new stringent classes of requirements imposed by such domains, especially implementation cost and energy efficiency. This Ph.D.

Finding SHA-2 Characteristics: Searching through a Minefield of Contradictions [PDF]

open access: yes, 2011
In this paper, we analyze the collision resistance of SHA-2 and provide the first results since the beginning of the NIST SHA-3 competition. We extend the previously best known semi-free-start collisions on SHA-256 from 24 to 32 (out of 64) steps and show a collision attack for 27 steps.

Effects of Isometric Hip Extension Using Thera-band on Hip Muscle Activities During Side-lying Hip Abduction Exercise in Participants With Gluteus Medius Weakness

open access: yesPhysical Therapy Korea
Background: Weakness of gluteus medius (Gmed) is related with musculoskeletal disorders. Individuals who experience weakness in the Gmed may activate the tensor fasciae latae (TFL) as a compensatory mechanism. Application of isometric hip extension (IHE)
