Review of Communication Protocols and Cryptographic Techniques Applied in Secure Token Transmission.

Abstract

Token transmission is a fundamental component in diverse domains, including computer networks, blockchain systems, distributed architectures, financial transactions, secure communications, and identity verification.Ensuring optimal performance during transmission is essential for maintaining the efficiency of data in transit. However, persistent threats from adversarial actors continue to pose significant risks to the integrity, authenticity, and confidentiality of transmitted data. This study presents a comprehensive review of existing research on token transmission techniques, examining the roles of transmission channels, emerging trends, and the associated security and performance implications. A critical analysis is conducted to assess the strengths, limitations, and applicability of various methods across different use cases, while identifying key advancements and enduring challenges. The findings aim to support researchers, practitioners and policymakers in selecting appropriate token transmission strategies and to provide a foundation for future innovations in this critical area.
