Real time packet-injection-loss resistant data source authentication protocol for group communication
There are three problems at present that SAIDA and eSAIDA can resist packet-loss but cannot resist packet-injection, and PRABS can resist packet-injection but the communication cost is too large. We propose a new real-time packet-injection-loss resistant data source authentication protocol (RPILRSA) in this paper. Using merkle hash tree, RPILRSA can discover the packets which are injected by the attacker before verifying the signature. Using erasure codes, this protocol can resist packet-loss in a certain extent, and realize real-time authentication by dividing data into blocks. Analysis shows that RPILRSA's communication cost is about 7%~9% of PRABS, and the cost of computing and verifying authentication information in RPILRSA is also less than in PRABS.
