5. LO! LLVM Obfuscator
   RIERA, FRANCISCO BLAS IZQUIERDO
   Examensarbete på avancerad nivå, 2014 (MSc - Computer Systems and Networks)
   As part of this Master’s Thesis some patches to LLVM have been written allowing the application of obfuscation techniques to the LLVM IR. These patches allow both obfuscation and polymorphism which results in code that is both hard to read and different from previous versions. This, makes finding the real changes made betweenversions harder for the attacker....

8. Session Management Algorithms for Solving K-Token Dissemination Using Network Coding
   GARCÍA, GUILLERMO BARREDO
   Examensarbete på avancerad nivå, 2014 (MSc - Computer Systems and Networks)
   In this thesis report we consider k-token dissemination algorithms that makes use of network coding. The k-token dissemination problem consists of propagating a total number of k tokens to all nodes in the network. The tokens are distributed between one or more nodes before the algorithm is executed, and the final goal is that all nodes must eventually have...
