  1. 1. Tree Structures in Broadcast Encryption

    Author : Kristin Anderson; Ingemar Ingemarsson; Jacob Löfvenberg; Robert Forchheimer; Ben Smeets; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Broadcast encryption; Subset Difference; tree structure; Information technology; Informationsteknologi;

    Abstract : The need for broadcast encryption arises when a sender wishes to securely distribute messages to varying subsets of receivers, using a broadcast channel, for instance in a pay-TV scenario. This is done by selecting subsets of users and giving all users in the same subset a common decryption key. READ MORE

  2. 2. Social Networks and Privacy

    Author : Oleksandr Bodriagov; Sonja Buchegger; Melek Ӧnen; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; social networks; privacy; decentralized; encryption-based access control; Computer Science; Datalogi;

    Abstract : Centralized online social networks pose a threat to their users’ privacy as social network providers have unlimited access to users’ data. Decentralized social networks address this problem by getting rid of the provider and giving control to the users themselves, meaning that only the end-users themselves should be able to control access of other parties to their data.

  3. 3. Aspects of Secure and Efficient Streaming and Collaboration

    Author : Gunnar Kreitz; Johan Håstad; Shai Halevi; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datalogi;

    Abstract : Research within the area of cryptography constitutes the core of this the- sis. In addition to cryptography, we also present results in peer-assisted streaming and web security. We present results on two specific cryptographic problems: broadcast encryption and secure multi-party computation. READ MORE
