Convolution: Math, Graphics, and Discrete Signals

250
In any LTI (Linear Time-Invariant) system, the convolution of two signals is denoted using a convolution operator, assuming all initial conditions are zero. The convolution integral can be divided into two parts: the zero-input or natural response and the zero-state or forced response, with t0 indicating the initial time.
To simplify the convolution integral, it is assumed that both the input signal and impulse response are zero for negative time values. The graphical convolution process...

Norton's Theorem01:14

Norton's Theorem

588
Norton's theorem is a fundamental principle stating that a linear two-terminal circuit can be substituted with an equivalent circuit, which comprises a current source (ⅠN) in parallel with a resistor (RN). Here, ⅠN represents the short-circuit current flowing through the terminals, and RN stands for the input or equivalent resistance at the terminals when all independent sources are deactivated. This implies that the circuit illustrated in Figure (a) can be exchanged with the...

Area of Science:

  • Computer Science
  • Information Security
  • Image Processing

Background:

  • Secure authentication of user data, especially images, is vital for digital banking, medical applications, and e-governance.
  • Conventional visual cryptographic protocols face challenges like high computational costs, multiple cover images, and reliance on third-party validation for image integrity.
  • Visual cryptography offers a simpler method by dividing images into shares for decryption without complex computations.

Purpose of the Study:

  • To introduce an optimized multi-tiered authentication protocol (OMTAP) integrated with a visual sharing scheme (VSS) for enhanced secure image sharing.
  • To address limitations of existing protocols by reducing share count, improving image fidelity, and ensuring transmission security.
  • To enable self-verification of decrypted image integrity, eliminating the need for external validation.

Main Methods:

  • Integration of the optimized multi-tiered authentication protocol (OMTAP) with a visual sharing scheme (VSS).
  • Implementation of asymmetric key matrix generators for self-verification of decrypted image integrity.
  • Reduction in the number of shares required for image reconstruction.

Main Results:

  • OMTAP demonstrated robustness and broad applicability in rigorous testing.
  • Decrypted images maintained high quality with a peak signal-to-noise ratio (PSNR) of 40 dB.
  • Full integrity of the decrypted images was confirmed at the receiver's end, validating the self-verification mechanism.

Conclusions:

  • OMTAP significantly improves secure image sharing protocols by enhancing efficiency and security.
  • The protocol's self-verification capability eliminates the need for external trust, making it suitable for sensitive data applications.
  • OMTAP ensures both the quality and integrity of shared images, crucial for informed decision-making across various sectors.
