摘要：Wireless reprogramming for a wireless sensor network is the process of uploading new code or changing thefunctionality of existing code. For security reasons, every code update must be authenticated to prevent an adversary frominstalling malicious code in the network. All existing reprogramming protocols are based on the centralized approach inwhich only the base station has the authority to initiate reprogramming. However, it is desirable and sometimes necessaryfor multiple authorized network users to simultaneously and directly reprogram sensor nodes without involving the basestation, which is referred to as distributed reprogramming. In this case, the network owner can also assign differentreprogramming privileges to different users. Motivated by this consideration, develop a secure and distributedreprogramming protocol named SDRP, which is the first work of its kind. The protocol uses identity-based cryptography tosecure the reprogramming and to reduce the communication and storage requirements of each node. Moreover, ourtheoretical analysis demonstrates the security properties of our protocol. It also implement SDRP in a network of resourcelimitedsensor nodes to show its high efficiency in practice.
