Abstract: In order to add more nodes’ provenances to the data packet, but not increase additional storage and computation burden, based on orthogonal code and message authentication code chain, this paper proposes a secure and effective provenance scheme (orthogonal code-based provenance scheme, OP) for wireless sensor network. The OP scheme can recover the transmission path of the data packet only using one packet, and the size of the provenance is independent of the path length. The security analysis shows that the OP scheme not only can resist the forgery provenance attack launched by single malicious node, but also can resist the deleting and inserting provenance attacks launched by multiple malicious nodes collusion, and it can locate the position of the malicious nodes. The performance analysis and simulation results show that compared with the existing schemes, the OP scheme has obvious advantages in storage space and energy consumption with the increase of path length.
