摘要：In wireless sensor networks (WSN's), the broadcast authentication is a critical securit y service, as it helps users to broadcast the WSN in an authenticable way. ¦Ì TESLA and MULTILEVEL ¦Ì TESLA are symmetric key based schemes, that have been introduced to provide such services for WSNs, but even they suffer from serious DoS attacks due to the delay in message authentication. Hence in order to overcome the weaknesses presented in the ¦Ì TESLA, and such similar schemes, this paper presents several effective key based schemes to achieve immediate broadcast authentication. In order to minimize the scheme overhead regarding the costs on both computation and communication, several schemes, such as hash tree and identity based signature schemes have been adopted. Of the proposed schem e, the quantitative energy consumption analysis is also given in detail. This paper is in all means prepared to solve the important multi sender broadcast authentication hindrance in WSNs
