摘要：Security has become one of the major issues for Data Communication over wired and wireless networks. In Wireless Sensor Networks (WSN), the hackers can inject false data via compro mised nodes and can able to alter the original files. There are many chances to perform a Denial Of Service (DOS) attack in WSNs. Initially send the D ynamic Key to all the cluster nodes followed by neighboring nodes. Then send the file which will be hidden and is secured by encrypting using Ad vanced Encryption Standard (AES) algorithm thereby mitigating from the DOS attack and Sybil attack. AES is secure enough to protect classified information up to the top Secret level, which is highest security. In a Sybil attacks, a malicio us user obtains multiple fake identities and pretends to be multiple, Distinct nodes in the system. If a compromised is made while file being sent, then the algorithm finds the affected node and informs to the user that DOS attack is done.
