Efficient Implementation of NIST LWC ESTATE Algorithm Using OpenCL and Web Assembly for Secure Communication in Edge...

Area of Science:

• Cybersecurity and Network Engineering
• Applied Cryptography
• Edge Computing Systems

Background:

• Edge computing relies heavily on wireless communication, necessitating robust data encryption for confidentiality and integrity.
• Optimizing cryptographic operations on both resource-constrained edge devices and high-throughput servers is crucial for efficient secure communication.
• Existing solutions may not adequately address the unique performance and universality requirements of edge computing security.

Purpose of the Study:

• To develop and present two versions of web-based security software for edge and server sides in edge computing environments.
• To implement and optimize the ESTATE (Energy efficient and Single-state Tweakable block cipher based MAC-Then-Encrypt) algorithm for secure data transmission.
• To enhance the performance of cryptographic operations using Web Assembly on edge devices and OpenCL on servers.

Main Methods:

• Developed universal, web-based security software executable on any browser for broad compatibility.
• Implemented the ESTATE algorithm using Web Assembly, optimizing performance through pre-computation of tweak values and efficient conditional statement handling.
• Utilized OpenCL with loop unrolling and optimized memory access for high-performance parallel encryption on server-side applications.
• Incorporated TweAES-128 and TweAES-128-6 with T-table methods and shuffling for AES-compatible, cache-timing attack-resistant operations.

Main Results:

• Demonstrated efficient implementation of the ESTATE algorithm via Web Assembly in major web browsers (Chrome, Firefox, Edge).
• Achieved significant performance improvements on the server-side using OpenCL, particularly through loop unrolling and optimized data handling.
• Validated the software's capability to provide both data confidentiality and authentication, covering essential security services for edge computing.

Conclusions:

• The developed web-based security software effectively addresses the need for secure and efficient communication in edge computing.
• The use of Web Assembly and OpenCL, along with algorithmic optimizations, provides a versatile and high-performance solution for edge and server security.
• The software's universality and focus on lightweight cryptography make it suitable for a wide range of edge devices and applications.
