Sammanfattning : Recent progress in the field of quantum computers provide radically improved muscles to search and sort in lists, solve systems of equations and prime factorize – virtues that inflict an immediate threat to the most common systems for public key cryptography used in a vast proportion of today’s computer networks. NTRUEncrypt is a lattice-based cryptography system which inhibits quantum computers for breaking the algorithm in polynomial time. LÄS MER

Sammanfattning : Efficient quantum computers will break most of today’s public-key cryptosystems. Therefore, the National Institute of Standards and Technology (NIST) calls for proposals to standardise one or more quantum-secure cryptographic schemes. LÄS MER

Sammanfattning : Lattice-based cryptography which holds a great promise for post-quantum cryptographyis naturally concerned by lattice reduction algorithms, the essential tools in the algorithmicstudy of lattices and its applications. In order to precisely estimate the securityparameters of these cryptosystems, it is a necessity to assess the practical diculty of theshortest vector problem (SVP) by analyzing the known ecient algorithms for solvingit.

Sammanfattning : There is a non-negligible risk that a quantum computer capable of breaking most modern public key encryption will be invented within the next couple of decades. All data that have to stay secret for more than 10-20 years should therefore be encrypted using quantum-resistant algorithms. LÄS MER

Sammanfattning : In a future full of quantum computers, new foundations for asymmetric cryptography are needed. We study the theoretical foundations for lattice-based cryptography as well as the current state on cryptographic attacks against them. We then turn our attention to signature systems and especially the system BLISS from 2013. LÄS MER
