1. Tree Structures in Broadcast Encryption
Sammanfattning : 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. LÄS MER
2. Social Networks and Privacy
Sammanfattning : Centralized online social networks pose a threat to their users’ privacy as social network providers have unlimited access to users’ data.

3. Aspects of Secure and Efficient Streaming and Collaboration
Sammanfattning : 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. LÄS MER
