This constitutes a serious problemfor modern digital communications, financial transactions, sensitive data, national security systems,healthcare records, intellectual property... Post-quantum cryptography (PQC) seeks to develop cryptographicprotocols resistant to quantum attacks, ensuring data security in a quantum-enabled future. Thispaper presents an analysis of various PQC algorithms, including lattice-based, code-based, hash-basedand multivariate polynomial. We analyze their theoretical foundations, security assumptions, and efficiency.Additionally, we provide a comparative study of these algorithms, highlighting their strengths andweaknesses in practical implementations. With this, we will provide a complete and detailed view of thecurrent state of post-quantum cryptography.
