Proper key management is crucial for maintaining the security of the hybrid solution. Regular Security Audits: Conduct regular security audits and penetration testing to identify and address any security weaknesses in the hybrid PQC solution. This proactive approach can help in detecting and mitigating vulnerabilities before they are exploited. Update and Patch Management: Stay updated with the latest security patches and updates for both quantum-resistant and classical cryptographic algorithms used in the hybrid solution. Timely updates can help in addressing known security vulnerabilities. User Training and Awareness: Provide training to users on best practices for using the hybrid PQC solution securely. Awareness programs can help in preventing common security threats such as phishing attacks or unauthorized access. Incident Response Plan: Develop a comprehensive incident response plan to effectively respond to security incidents or breaches in the hybrid PQC solution. Having a well-defined plan can minimize the impact of security incidents. By implementing these security measures, organizations can effectively mitigate the potential risks associated with hybrid PQC solutions and ensure the security of their cryptographic infrastructure.

Core Concepts

Migrating existing software systems and networks to post-quantum cryptography is necessary to ensure long-term security, but the process is complex and lacks clear guidance.

Abstract

This systematic literature review examines the current state of research on migrating software systems towards post-quantum cryptography (PQC). The key findings are:

Migration Process:

The migration process can be divided into four main phases: Diagnosis, Planning, Execution, and Maintenance.
The Diagnosis phase involves asset identification, risk assessment, cryptographic inventory, and cryptographic assessment.
The Planning phase includes cryptographic prioritization and developing a migration plan.
The Execution phase focuses on implementing the migration, often using hybrid solutions combining classical and quantum-resistant cryptography.
The Maintenance phase ensures the migrated systems remain secure over time.

PQC Applications:

Hybrid PQC solutions, combining classical and quantum-resistant cryptography, are commonly used during migrations.
A variety of software systems have been migrated, including web servers, databases, blockchain frameworks, and messaging applications.
Key standards like TLS, X.509, and S/MIME have been adapted to incorporate PQC.

Challenges:

Lack of experience and high effort required for PQC migration
Concerns about the security of the post-migration system
High complexity due to the diverse requirements and constraints of existing protocols and implementations

The literature highlights the need for more comprehensive guidance and best practices for PQC migration. Current approaches are mostly experimental, leading to an overall chaotic situation that this review aims to clarify.
