Study Security Cloud with SHA-2 Algorithm

, 2023
This study explores the relationship between cloud computing and security, concentrating on the use of the SHA-2 cryptographic algorithm. Due to the distributed and shared nature of cloud settings, cloud computing has transformed how information and services are accessed and provided. However, it has also created new security issues.

Preimage Attacks on Reduced Tiger and SHA-2 [PDF]

, 2009
This paper shows new preimage attacks on reduced Tiger and SHA-2. Indesteege and Preneel presented a preimage attack on Tiger reduced to 13 rounds (out of 24) with a complexity of 2128.5. Our new preimage attack finds a one-block preimage of Tiger reduced to 16 rounds with a complexity of 2161. The proposed attack is based on meet-in-the-middle attacks.

Redefining Therapies for Drug‐Resistant Tuberculosis: Synergistic Effects of Antimicrobial Peptides, Nanotechnology, and Computational Design

Advanced Healthcare Materials, EarlyView.
Antimicrobial peptide (AMP)‐loaded nanocarriers provide a multifunctional strategy to combat drug‐resistant Mycobacterium tuberculosis. By enhancing intracellular delivery, bypassing efflux pumps, and disrupting bacterial membranes, this platform restores phagolysosome fusion and macrophage function.

Flexoelectrically Induced Polar Topology in Twisted SrTiO3 Membranes

Advanced Materials, EarlyView.
Twisted SrTiO3 bilayers host polar vortices of flexoelectric origin, revealed through combined experiment and theory. By reconstructing polarization from the toroidal moment of strain gradients, the work establishes a 3D chiral state with broken inversion and mirror symmetries.

Routing Using Trust Based System with SHA-2 Authentication

Procedia Computer Science, 2015
AbstractMobile Ad hoc NETwork (MANET) is an infrastructure independent network with every mobile node acting as the router in the network formation. These networks are most useful when the present infrastructure is destroyed or at remote locations which are deprived of these amenities.
