1. 1. On Some Symmetric Lightweight Cryptographic Designs

   Författare :Martin Ågren; Institutionen för elektro- och informationsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lightweight cryptography; integrity; authentication; symmetric cryptography; stream ciphers; block ciphers; Grain-128a; BEAN; KTANTAN; textsc{PRINTcipher}; FCSR combiner; related-key attack; linear cryptanalysis; linear correlations; invariant subspace attack.;

   Sammanfattning : This dissertation presents cryptanalysis of several symmetric lightweight primitives, both stream ciphers and block ciphers. Further, some aspects of authentication in combination with a keystream generator is investigated, and a new member of the Grain family of stream ciphers, Grain-128a, with built-in support for authentication is presented.

   Sammanfattning : The Internet of Things (IoT) is increasingly becoming an integral component of many applications in consumer, industrial and other areas. Notions such as smart industry, smart transport, and smart world are, in large part, enabled by IoT. LÄS MER

4. 3. Design and Implementation of Efficient and Secure Lightweight Cryptosystems

   Författare :Shohreh Sharif Mansouri; Elena Dubrova; Vincent Rijmen; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : In recent years there has been a wide-spread deployment of battery-powered and passive devices such as RFID tags, systems with very strong limitations on area, cost and power budgets. Deploying cryptographic solutions for these systems is both important, because it could unlock several security-critical applications, and challenging, due to the stringent budgets: the overheads of even the smallest block ciphers are often one or more orders of magnitude too high.

5. 4. Public Key Infrastructure and its applications for resource-constrained IoT

   Författare :Joel Höglund; Shahid Raza; Thiemo Voigt; Andrei Gurtov; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; IoT; PKI; cybersecurity; security; asymmetric cryptography; Contiki-NG; Computer Science with specialization in Computer Communication; Datavetenskap med inriktning mot datorkommunikation;

   Sammanfattning : The Internet of Things (IoT) is rapidly expanding and IoT devices are being deployed in security-critical scenarios, such as in critical infrastructure monitoring and within e-health, and privacy-sensitive applications in hospitals and homes. With this, questions of security and safety become paramount. LÄS MER

7. 5. Using Coding Techniques for Attacking Post-Quantum Cryptographic Assumptions and Systems

   Författare :Qian Guo; Institutionen för elektro- och informationsteknik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Post-quantum cryptography for resisting possible attacks from malicious quantum adversaries has become one of the key topics in recent cryptographic research. Its ultimate goal is to search for efficient and secure primitives replacing the factoring- and discrete log-based schemes in service that will be broken in polynomial time by Shor’s algorithm.
