Soft Analytical Side-Channel Attacks on SHA-2 and HMAC

Transactions on Cryptographic Hardware and Embedded Systems
We 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 ...

On the exploitation of a high-throughput SHA-256 FPGA design for HMAC [PDF]

ACM Transactions on Reconfigurable Technology and Systems, 2012
High-throughput and area-efficient designs of hash functions and corresponding mechanisms for Message Authentication Codes (MACs) are in high demand due to new security protocols that have arisen and call for security services in every transmitted data packet. For instance, IPv6 incorporates the IPSec protocol for secure data transmission. However, the

How Much to Sell and When: Optimal Staged Divestiture of Patent‐Linked Royalty Claims Under Risk, Illiquidity, and Finite Horizon

Managerial and Decision Economics, EarlyView.
ABSTRACT Patent owners can sell a royalty interest in stages rather than all at once. This paper asks how much to sell now when claim values are uncertain, buyers are costly to reach, and patent expiry limits the time available. A decision model produces sale schedules that adjust to current value, the share retained, and time remaining.

Practical considerations for pathologists when selecting digital pathology systems: an ESDIP guide

The Journal of Pathology, EarlyView.
Abstract The implementation of digital pathology (DP) has been reported across academic, public, and private laboratory settings, providing valuable insights into workflow transformation. However, comparatively little guidance exists on how DP systems should be evaluated prior to acquisition and deployment.

Diagnostic Accuracy of 12‐Lead ECG Algorithms for Accessory Pathway Localization in WPW: A Meta‐Analysis

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Background In Wolff–Parkinson–White (WPW) syndrome, accurate localization of accessory pathways before catheter ablation can improve procedural planning and efficiency. Several 12‐lead electrocardiographic (ECG) algorithms have been proposed, but their diagnostic performance has not been consistently established.

Engineered surface strategies to manage dental implant‐related infections

Periodontology 2000, EarlyView.
Abstract When exposed to the oral environment, dental implants, like natural surfaces, become substrates for microbial adhesion and accumulation, often leading to implant‐related infections—one of the main causes of implant failure. These failures impose significant costs on patients, clinicians, and healthcare systems.
