By functionally decomposing a specific algorithm (the hierarchical secure aggregation algorithm of Chan et al. [3] and Frikken et al. [7]), we uncover a useful general functionality which we use to generate various efficient network security primitives, including: a signature scheme ensuring authenticity, integrity and non-repudiation for arbitrary node-to-node communications; an efficient broadcast authentication algorithm not requiring time synchronization; a scheme for managing public keys… CONTINUE READING
