Today information security is foremost demand of every application. Data confidentiality is really a challenging task for Wireless Sensor Networks (WSNs). A light weight and full proof security algorithm is introduced in this research paper. The authors have named it "Source ID Based Security (SIBS)" algorithm. SIBS algorithm involves the identification of sender node that is changed after fixed interval of time to mislead the attacker. Results have shown that proposed algorithm provides 7% resistance to different types of well known attacks including Eavesdropping, Denial Of Service (DOS) and false insertion of data. The simulation has been carried out using TOSSIM simulator.
