Challenges in Traditional Cryptography

In the current digital environment, traditional cryptography faces several challenges, particularly as technology advances and cyber threats become more complex. The following are some significant obstacles:

Key Management

Managing keys is one of the main issues with classical cryptography. Encryption and decryption in cryptographic systems depend on keys; therefore, creating, distributing, and securely storing keys becomes essential. As the number of communication parties increases, key management becomes more complex, increasing the risk of vulnerabilities if keys are lost, stolen, or mishandled.

Algorithm Vulnerabilities

As processing power and algorithmic advances increase, classic cryptographic algorithms such as RSA and AES are increasingly vulnerable to attacks. Data security can be compromised by cryptanalytic techniques such as side-channel attacks, differential cryptanalysis, and brute-force attacks, which exploit flaws in algorithms or implementations.

Quantum Computing Threat

The development of quantum computing presents a danger to established cryptography. Widely used encryption techniques like RSA and ECC could be broken by quantum computers using efficient factoring algorithms such as Shor’s algorithm. The creation and implementation of cryptographic protocols and algorithms that are resistant to quantum technology is crucial.

Key Exchange over Unsecured Channels

It might be difficult to securely exchange cryptographic keys over unprotected channels, such as the Internet. Strong key exchange protocols, such as the Diffie-Hellman key exchange, are essential because they can prevent man-in-the-middle attacks, in which an attacker intercepts and modifies key exchange messages, jeopardising the confidentiality and integrity of communication channels.

Quantum Key Distribution

Given the potential threat quantum computing poses to traditional secret-key systems, quantum key distribution (QKD) is essential for maintaining communication security. Quantum-based keys are required for secure Internet of Things communication, as quantum computers frequently compromise asymmetric key schemes. These quantum keys establish a secure channel between communicating entities by leveraging concepts from quantum mechanics. Secure quantum key distribution techniques include those found in BB84, BBM92, SARG04, and E91, among others. The goal of QKD is key distribution and transmission via both quantum and conventional channels. To minimise the amount of information extracted from the quantum system in accordance with the principles of quantum physics, the key distribution approach involves sharing random bits on a random basis.

Quantum Authentication

The security of messages depends on quantum authentication to verify message confidentiality and integrity. Verification of messages, integrity, and non-repudiation are guaranteed via mutual authentication between entities. Quantum Signature and Entanglement are two techniques used in quantum-based identity identification. A special characteristic of quantum communication is quantum entanglement, in which entangled particles have interdependent states that are represented as Bell states. To provide non-repudiation and defend against user impersonation attacks, quantum signature protocols, such as quantum group signature, quantum blind signature, and arbitrated quantum signature, are used to verify the identities of authenticated users.
