A new aggregate signature scheme for secure data verification in WSN

P Vinodkumar, S Srinivas


We prepare an ID-based aggregate signature system for WSNs, which can compress many signatures generated by sensor nodes into a short one, i.e., it can reduce the communication and storage cost. Furthermore, we have proved that our IBAS scheme is secure in random oracle model based on the CDH statement, and we also have verified that our aggregate signature can resist association attacks, that is to say the aggregate signature is valid if and only if every single signature used in the aggregation is valid.
