Broadcast is an important mechanism for large scale information dissemination, in satellite-based communications, wireless networks, and the Internet. Security is central for broadcast applications: (1) data injection or message spoofing is easy in many broadcast networks, so the receivers need to verify the authenticity of messages they receive; (2) anybody can receive broadcast packets, so applications require technologies to restrict access to content to legitimate receivers.

520 $a Broadcast is an important mechanism for large scale information dissemination, in satellite-based communications, wireless networks, and the Internet. Security is central for broadcast applications: (1) data injection or message spoofing is easy in many broadcast networks, so the receivers need to verify the authenticity of messages they receive; (2) anybody can receive broadcast packets, so applications require technologies to restrict access to content to legitimate receivers.
520 $a The nature of broadcast communication makes it particularly challenging to provide the desired security properties: (1) in many broadcast networks, packets may get lost, and lost packets are often not retransmitted (to achieve scalability); (2) many broadcast applications require to process data as soon as the packets arrive; (3) receivers are heterogenous, with widely varying bandwidth and computation resources; (4) the group of receivers may be dynamic, with members joining and leaving the group at any time.
520 $a In my thesis, I designed and built a suite of new efficient security protocols to enable broadcast authentication (TESLA & BiBa), broadcast signature (HTSS & MESS), and key distribution for large dynamic groups (ELK). These protocols have high efficiency and scalability, and can tolerate high packet loss. Moreover, I have built efficient, secure communication for sensor networks using these protocols, demonstrating that these protocols are practical even for resource-starved sensors.
