N2 - Wireless Sensor Networks (WSNs) consist of highly resource constrained sensor nodes. A large number of sensor nodes are deployed over a wide geographical area and operate in unattended fashions. These features of WSNs make difficult the manual intervention through physical access. Thus, secure network reprogramming is a critical requirement for WSNs. So far, the previous studies have focused only on the authenticity and integrity of program images. However, the delayed authentication problem caused by the packet loss should be considered. In this paper, we propose two schemes in the way of providing the recovery method for verification processes at packet loss, using supplementary hashing: Redundant Hash scheme and Page Digest scheme. Our schemes show improved performance than previous studies.
