1. 1. Side-Channel Analysis of Post-Quantum Cryptographic Algorithms

   Författare :Kalle Ngo; Johnny Öberg; Ingo Sander; Elena Dubrova; Lejla Batina; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Side-channel attack; Post-quantum cryptography; Deep learning; LWE LWR-based KEM; Hardware security; Sidokanalsattack; Postkvantkryptering; Djupinlärning; LWE LWR-baserad KEM; Hårdvarusäkerhet; Informations- och kommunikationsteknik; Information and Communication Technology;

   Sammanfattning : Public key cryptographic schemes used today rely on the intractability of certain mathematical problems that are known to be efficiently solvable with a large-scale quantum computer. To address the need for long-term security, in 2016 NIST started a project for standardizing post-quantum cryptography (PQC) primitives that rely on problems not known to be targets for a quantum computer, such as lattice problems.

3. 2. Deep Learning Side-Channel Attacks on Advanced Encryption Standard

   Författare :Huanyu Wang; Elena Dubrova; Mark Smith; Francesco Regazzoni; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Side-channel attack; Deep learning; Advanced Encryption Standard; Hardware security; Informations- och kommunikationsteknik; Information and Communication Technology;

   Sammanfattning : Side-channel attacks (SCAs) have become one of the most realistic threats to implementations of cryptographic algorithms. By exploiting the nonprime, unintentional physical leakage, such as different amount of power consumed by the device during the execution of the cryptographic algorithm, SCAs are able to bypass the theoretical strength of cryptography and extract the secret key.

4. 3. Securing the Memory Hierarchy from Speculative Side-Channel Attack

   Författare :Christos Sakalis; Magnus Själander; Sven Karlsson; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Science; Datavetenskap;

   Sammanfattning : Modern high-performance CPUs depend on speculative out-of-order execution in order to offer high performance while also remaining energy efficient. However, with the introduction of Meltdown and Spectre in the beginning of 2018, speculative execution has been under attack. LÄS MER

5. 4. Decryption Failure Attacks on Post-Quantum Cryptography

   Författare :Alexander Nilsson; Institutionen för elektro- och informationsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Post-quantum cryptography; Code-based cryptography; Lattice-based cryptography; side-channel attack;

   Sammanfattning : This dissertation discusses mainly new cryptanalytical results related to issues of securely implementing the next generation of asymmetric cryptography, or Public-Key Cryptography (PKC).PKC, as it has been deployed until today, depends heavily on the integer factorization and the discrete logarithm problems.

7. 5. Adaptive Microarchitectural Optimizations to Improve Performance and Security of Multi-Core Architectures

   Författare :Nadja Holtryd; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multi-Core Architectures; Bandwidth Partitioning; Prefetch Throttling; Cache Partitioning; Microarchitectural Optimizations; Side-channel Attacks;

   Sammanfattning : With the current technological barriers, microarchitectural optimizations are increasingly important to ensure performance scalability of computing systems. The shift to multi-core architectures increases the demands on the memory system, and amplifies the role of microarchitectural optimizations in performance improvement. LÄS MER
