Additively Manufacturable High‐Strength Aluminum Alloys with Coarsening‐Resistant Microstructures Achieved via Rapid Solidification

Advanced Materials, EarlyView.
Rapid solidification in laser additive manufacturing facilitates the precipitation of metastable phases in aluminum alloys. These metastable phases significantly enhance the strength by forming a high‐volume fraction of precipitates with an order of magnitude reduced sizes and smaller interspacing, effectively impeding dislocation motion. Consequestly,

SE-Enc: A Secure and Efficient Encoding Scheme Using Elliptic Curve Cryptography

IEEE Access, 2019
Many applications use asymmetric cryptography to secure communications between two parties. One of the main issues with asymmetric cryptography is the need for vast amounts of computation and storage.

Relation of Continuous Chirality Measure to Spin and Orbital Polarization, and Chiroptical Properties in Solids

Advanced Optical Materials, EarlyView.
This work quantifies chirality through the continuous chirality measure (CCM). The CCM is correlated to a variety of properties: spin‐orbit field, orbital angular momentum, circular dichroism, absorption dissymmetry factor (gCD) and the circular photogalvanic effect.

Phase-Image-Encryption-Based Elliptic Curve and Double-Random-Phase Encoding

Engineering Proceedings
In this paper, we proposed an enhanced asymmetric cryptosystem scheme for image encryption using a combination of Elliptic Curve and Fourier transformations. Our proposed encryption and decryption process is highly secure with a smaller key size compared

Secure Image Transmission Using Chaotic-Enhanced Elliptic Curve Cryptography

IEEE Access, 2020
In this paper, a novel scheme for secure and real time image transmission is introduced. The scheme uses a block-based elliptic curve (BBEC) public key encryption as a first stage of encryption so it solves the key distribution and management problem of ...

Enhanced Elliptic Curve Cryptography

Indian Journal of Science and Technology, 2015
Background/Objectives: Today’s Technological world Information Security is an essential for commercial and legal trading, secrecy, truthfulness and non-reputability. The Elliptic Curve Cryptography (ECC) has become one of the latest trends in the field of Public-Key Cryptography (PKC). ECC promises a faster, efficient and more secured.
