Hochschild homology, Frobenius homomorphism and Mac Lane homology [PDF]

open access: yesAlgebraic & Geometric Topology, 2007
The article begins with the elementary but striking observation that all higher homotopy groups of a simplicial ring where \(x^m = x\) holds for some \(m \geq 2\) are zero. This is the key fact which is then used to compute the Hochschild homology of any commutative \(\mathbb F_p\)-algebra \(A\) with coefficients in \(A\) twisted by the Frobenius ...

A generic homomorphic MAC construction for authentication in network coding

open access: yesSecurity and Communication Networks, 2013
ABSTRACTIn this paper, we propose a generic homomorphic MAC scheme on the basis of linear mapping over finite fields. Benefiting from its algebra characteristics, our scheme is more flexible and effective than the previous schemes based on the vector inner product or the trace function over finite fields.

Portability in MAC protocol and transceiver software implementations for LR-WPAN platforms [PDF]

open access: yes, 2010
In a variety of emerging networked computing system domains over the years, there have been bursts of activity on new medium access control (MAC) protocols, as new communication transceiver technologies with greater data-movement performance or lower ...

Pathological Roles of Astrocytes in Traumatic Brain Injury

open access: yesCNS Neuroscience &Therapeutics, Volume 32, Issue 4, April 2026.
TBI induces intrinsic astrocytic changes, including reactive astrogliosis, A1 and A2 polarization, ion channels activation, pathological edema, oxidative stress, and metabolic dysregulation. These injury‐responsive astrocytes regulate neuroinflammation and tissue remodeling through dynamic crosstalk with microglia, macrophages, vascular endothelial ...

Decentralized Privacy Preserving Data Sharing Model for Electronic Health Records (EHR) Using Blockchain Technology

open access: yesIET Blockchain, Volume 6, Issue 1, January/December 2026.
This article talks about blockEHR Healthcare providers can validate raw physiological data with the help of IoMT devices and edge computing role‐based access control (RBAC). ABSTRACT In centralized systems prone to data breaches and single points of failure, issues about security, privacy, scalability, and real‐time sharing of electronic health records

Towards Secure Biometric Solutions: A Multifactor Authentication Framework for Facial Recognition While Protecting User Data

open access: yesIET Biometrics, Volume 2026, Issue 1, 2026.
Storing raw facial images or face embeddings in an authentication database creates a persistent privacy liability. A single breach can permanently expose a person’s biometric identity. This paper presents a multifactor authentication (MFA) framework for facial recognition systems that removes this liability by never storing biometric data, in any form,

Lightweight Mutual Authentication in VANETs: A Software‐Defined Networking and Edge Computing Approach

open access: yesIET Communications, Volume 20, Issue 1, January/December 2026.
This paper presents a lightweight mutual authentication protocol for VANETs that integrates SDN, edge computing, and ECC to achieve low‐latency, scalable, and privacy‐preserving vehicle communication. The proposed system reduces authentication delay and computational overhead while supporting batch verification and conditional identity traceability ...

Committed MPC - Maliciously Secure Multiparty Computation from Homomorphic Commitments [PDF]

open access: yes, 2018
We present a new multiparty computation protocol secure against a static and malicious dishonest majority. Unlike most previous protocols that were based on working on MAC-ed secret shares, our approach is based on computations on homomorphic commitments

On the Security of Lightweight Homomorphic Obfuscation for Protecting Against Hardware Trojans

open access: yesTransactions on Cryptographic Hardware and Embedded Systems
Hardware Trojan (HT) attacks pose a critical threat to modern microelectronics by enabling the leakage of sensitive information, such as cryptographic keys, or by inducing functional faults.

MPC‐Facilitated Adaptive Security Framework for BFT Protocols

open access: yesIET Information Security, Volume 2026, Issue 1, 2026.
The growing use of blockchain and distributed systems requires Byzantine fault tolerant (BFT) protocols that remain secure under dynamic adversaries. However, existing BFT protocols often rely on static assumptions and lack clear mechanisms to detect and remove malicious or denial‐of‐service (DoS) nodes during execution.
