Post-Quantum Cryptography : 8th International Workshop, PQCrypto 2017, Utrecht, The Netherlands, June 26-28, 2017, Proceedings

The book Post-Quantum Cryptography: 8th International Workshop, PQCrypto 2017, Utrecht, The Netherlands, June 26-28, 2017, Proceedings serves as an indispensable resource for researchers, scholars, and practitioners exploring the emerging field of post-quantum cryptography (PQC). As quantum computing continues to advance, the need for cryptographic systems that are impervious to quantum attacks has become increasingly urgent. This comprehensive volume, edited by Tanja Lange and Tsuyoshi Takagi, encapsulates the latest research, challenges, and advancements in the promising domain of PQC. It compiles a collection of curated, peer-reviewed papers presented during the 8th PQCrypto workshop, offering in-depth insights into cryptographic solutions that retain their security even in the post-quantum era.

Detailed Summary of the Book

The book opens with an introduction to the pressing need for post-quantum cryptography as quantum computers, such as those designed by entities like Google and IBM, threaten the viability of traditional cryptographic protocols—especially those relying on the hardness of factorization (RSA) or discrete logarithms (ECC). The proceedings bring together cutting-edge work on cryptosystems immune to quantum attacks, covering topics such as lattice-based cryptography, code-based cryptography, multivariate quadratic-equations-based systems, hash-based signatures, and more.

The collection of papers presented spans from theoretical breakthroughs to practical implementations. It addresses the development of new algorithms, security proofs under quantum adversarial models, and performance optimization to make these systems feasible for real-world applications. With contributions from leading experts in the field, this volume reflects both the depth and breadth of PQC research. Furthermore, it discusses ongoing standardization efforts, led by organizations like NIST, that aim to define cryptographic transition paths in preparation for the coming era of quantum computers.
