1. Exposing memory accesses and branches in machine code to symbolic execution : Tracking instructions through binary raising
Master-uppsats, Linköpings universitet/Programvara och systemSammanfattning : In 2018, a new security vulnerability was discovered that existed in billions of processors from different manufacturers, using various architectures. A so-called spectre attack can be launched to exploit the vulnerability and cause cryptographic information to leak through side-channels of the targeted system. LÄS MER
2. Clueless: A Tool Characterising Values Leaking as Addresses : Clueless: A Tool Characterising Values Leaking as Addresses
Master-uppsats, Uppsala universitet/Institutionen för informationsteknologiSammanfattning : A fundamental programming feature that allows Spectre to effortlessly leak the value of secrets via cache side channels is the transformation of data values into addresses. Consider forexample sorting, hashing, or many other algorithms that create addresses based on datavalues. LÄS MER
3. Automated checking of programming assignments using static analysis
Kandidat-uppsats, Mälardalens högskola/Akademin för innovation, design och teknikSammanfattning : Computer science and software engineering education usually contain programming courses that require writing code that is graded. These assignments are corrected through manual code review by teachers or course assistants. The large amount of assignments motivates us to find ways to automatically correct certain parts of the assignments. LÄS MER
4. Growth and Characterization of Ferroelectric Lanthanum-Doped Hafnia
Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionenSammanfattning : Hafnia-based ferroelectrics show great promise as future nonvolatile memory devices, however, their issues regarding device inconsistency across their lifetime, coupled with the relatively short total lifetime, makes these devices only theoretical as of now. In this thesis, an ALD deposition recipe for lanthanum oxide deposition was created. LÄS MER
5. Efficient Cache Randomization for Security
Master-uppsats, Uppsala universitet/Institutionen för informationsteknologiSammanfattning : The effectiveness of cache hierarchies, undeniably, is of crucial importance, since they essentially constitute the solution to the disparity between fast processors and high memory latency. Nevertheless, security developments spanning for more than the last decade, critically expose cache hierarchies' vulnerabilities, thus creating a need for counter-measures to take place. LÄS MER
