1. On Some Symmetric Lightweight Cryptographic Designs
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.

2. Life of a Security Middlebox : Challenges with Emerging Protocols and Technologies
Sammanfattning : The Internet of today has intermediary devices known as middleboxes that perform more functions than the normal packet forwarding function of a router. Security middleboxes are a subset of these middleboxes and face an increasingly difficult task to perform their functions correctly. LÄS MER
3. Some Words on Cryptanalysis of Stream Ciphers
Sammanfattning : In the world of cryptography, stream ciphers are known as primitives used to ensure privacy over a communication channel. One common way to build a stream cipher is to use a keystream generator to produce a pseudo-random sequence of symbols. LÄS MER
4. Trust but verify: trust establishment mechanisms in infrastructure clouds
Sammanfattning : In the cloud computing service model, users consume computation resources provided through the Internet, often without any awareness of the cloud service provider that owns and operates the supporting hardware infrastructure. This marks an important change compared to earlier models of computation, for example when such supporting hardware infrastructure was under the control of the user. LÄS MER
5. MobiLeak : Security and Privacy of Personal Data in Mobile Applications
Sammanfattning : Smartphones and mobile applications have become an essential part of our daily lives. People always carry their smartphones with them and rely on mobile applications for most of their tasks: from checking emails for personal or business purposes, to engaging in social interactions via social networks, from trading online or checking their bank accounts to communicating with families and friends through instant messaging applications.
