摘要：Wireless reprogramming in a wireless sensor network (WSN) is the process of propagating a new code image or relevant commands to sensor nodes. As a WSN is usually deployed in hostile environments, so for security reasons every code update must be authenticated to prevent an adversary from installing malicious code in the network. The reprogramming protocols based on the distributed reprogramming approach allow multiple authorized network users to simultaneously and directly reprogram sensor nodes without involving the base station. SDRP is the first distributed reprogramming protocol. In this research Elliptic Curve Integrated Encryption Scheme is used for providing strong security to sensor network. Only authorized users will be allowed to update the system reprogramming and with according to privileges carried by user, system upgrade options will be provided. User privilege and identity will be checked with signature of the message. For managing privacy preservation between owner and other user's different session keys for owner and users are introduced so that both can have different views of network and can also preserve their privacy from each other
