Introduction: Because it aids in shielding private information and communications from prying eyes, cryptography is a crucial component of contemporary society. The advent of quantum computing, however, has made conventional cryptographic techniques that depend on the difficulty of computing discrete logarithms or factoring large numbers more open to attack. Post-quantum cryptography, a subfield of cryptography that focuses on creating algorithms defensible against both quantum and classical computers, enters the picture here.
The foundation of post-quantum cryptography is a class of mathematical problems known as lattice-based, code-based, multivariate-based, or hash-based problems that are thought to be challenging for quantum computers to solve. These algorithms were created to withstand quantum attacks, which employ quantum computers to compromise more established cryptographic algorithms. Even if a hacker possesses a quantum computer, post-quantum cryptography prevents them from decrypting the data and gaining access to confidential data.
Quantum computing is still in its early stages, but it has the potential to revolutionize the field of cryptography, which is why post-quantum cryptography is important. In the face of quantum attacks, which can jeopardize the security of confidential data and communications, conventional cryptographic algorithms will become obsolete. Because it addresses the issue of quantum attacks and ensures that data and communications are secure even in the face of quantum computing, post-quantum cryptography is crucial.
Post-quantum cryptographic developments at the moment include the creation of lattice-based, code-based, multivariate-based, and hash-based algorithms. Since 2016, the National Institute of Standards and Technology (NIST) has been working to standardize post-quantum cryptographic algorithms, and the last round of candidate algorithm submissions was finished in 2022. The next step is to choose the most promising algorithms and develop implementation standards for them.
In conclusion, post-quantum cryptography is a vital area of research that protects data and communications from quantum attacks. Post-quantum cryptography is a crucial area of research because traditional cryptographic algorithms are becoming more and more vulnerable as a result of the development of quantum computing. Future data and communications can be kept secure as more post-quantum cryptographic algorithms are created and standardized.
