What is crypto protocol? 

A cryptographic protocol, at its core, is a distributed algorithm designed to ensure secure communication within an insecure environment, such as the internet or wireless networks. These protocols are fundamental in various applications, including electronic payments, electronic voting, and database access systems, due to their ability to solve problems related to secrecy, authentication, integrity, and protection against dishonest individuals . Cryptographic protocols employ a series of steps or rules that endpoints in a telecommunication connection follow, specifying interactions between communicating entities across different levels of a telecommunication exchange. This structured approach is crucial for maintaining the security and integrity of data interchange, whether at the hardware device level or the application program level . The development and implementation of cryptographic protocols involve the use of cryptographic mechanisms and algorithms to provide security assurances, such as confidentiality, integrity, authentication, and non-repudiation . These protocols can address classic problems like the distribution of keys, which are vulnerable to interception, by eliminating the need for key exchanges through authentication protocols and other cryptographic techniques . Moreover, cryptographic protocols are designed with mathematical models to justify their correctness and safety, ensuring that errors, which could lead to significant financial and social damage, are minimized . In addition to traditional applications, cryptographic protocols are also being adapted for modern challenges, such as securing data communication in wired networks of security systems and enhancing the security and scalability of public blockchains . They play a fundamental role in distributed systems, especially in scenarios where operations must be secure in the presence of adversaries, by facilitating agreement among parties on shared keys or other values necessary for secure transactions . Furthermore, cryptographic protocols are evolving to include biometric verification for additional layers of security, combining the advantages of biometric authentication with the robustness of public key cryptography .
