Broadcast authentication is a vital security primitive for the management of a copious number of parties. In the universally composable framework, this paper investigates broadcast authentication using one-time signature based on the fact that one-time signature has efficient signature generation and verification suitable for low-power devices, and gives immediate authentication, which is a favorable property for time-critical messages. This paper first formulates a broadcast authentication… CONTINUE READING
