Scanning Electron Microscopy

Scanning Electron Microscopy

A scanning electron microscope (SEM) is used to study the surface features of a sample by using an electron beam that scans the sample surface in a two-dimensional manner. Typically, areas between ~1 centimeter to 5 micrometers in width can be imaged. SEM can be used to image bacteria, viruses, tissues as well as larger samples like insects. Conventional SEM gives a magnification ranging from 20X to 30,000X and spatial resolution of 50 to 100 nanometers.

Inductively Coupled Plasma Atomic Emission Spectroscopy: Instrumentation

Inductively Coupled Plasma Atomic Emission Spectroscopy: Instrumentation

Inductively coupled plasma (ICP) is the common plasma source used in atomic emission spectroscopy (AES), a technique that detects and analyzes various elements in a sample. This method is often called inductively coupled plasma atomic emission spectroscopy (ICP-AES).
There are three main types of inductively coupled plasma atomic emission spectroscopy (ICP-AES) instruments: sequential, simultaneous multichannel, and Fourier transform instruments, with the latter being less commonly used....

Confocal Fluorescence Microscopy

Confocal Fluorescence Microscopy

Confocal microscopy is an advanced microscopic technique. The prime advantage of the confocal microscope over other microscopy techniques is its ability to block the out-of-focus light from the illuminated samples using pinholes. It is widely used with fluorescence optics to obtain high-resolution, sharp contrast images. Unlike optical microscopes, confocal microscopes use a focused beam of light laser to scan the entire sample surface at different z-planes. These microscopes are, therefore,...

Area of Science:

Cryptography
Optical Information Processing
Biometrics

Background:

Traditional Optical Scanning Cryptography (OSC) faces challenges in key management and dispatch.
Elliptic Curve Cryptography (ECC) offers robust security but requires integration with other cryptographic methods for specific applications.

Purpose of the Study:

To develop a novel asymmetric cryptosystem integrating OSC and ECC.
To enhance the security and overcome key management issues in OSC.
To leverage biometric data for secure cryptographic key generation.

Main Methods:

Encryption involves generating cosine and sine holograms using pupil functions derived from a sender's biometric private key via ECC.
These holograms are further encrypted into ciphertext using the ECC algorithm.
Decryption utilizes the receiver's distinct biometric private key.

Main Results:

The proposed system functions as an asymmetric cryptosystem, differentiating sender and receiver keys.
It effectively addresses key management and dispatch problems inherent in conventional OSC.
Demonstrated superior security strength compared to standard OSC methods.
Feasibility confirmed through both numerical simulations and experimental validation.

Conclusions:

The integrated OSC and ECC approach provides a secure and efficient asymmetric cryptosystem.
Biometric-based key generation enhances the security of holographic data.
The method offers a viable solution for secure communication in optical information processing.
