Security Protocols for Broadcast Communications

	Mr.Perrig describes how he designed and built a suite of new efficient security protocol families to enable broadcast authentication (TESLA & BiBa), broadcast signature (HTSS & MESS), and key distribution for large dynamic groups (ELK). His protocols are efficient, scalable, and tolerate high packet loss. He also discusses an implementation on a secure sensor network using nodes with sharply limited resources (8-bit microprocessor, 8-K ROM, 512 bytes RAM, limited battery life).
