Abstract :

Sensor networks are expected to play an essential role in the upcoming age of pervasive computing. Due to their constraints in computation, memory, and power resources, their susceptibility to physical capture, and use of wireless communications, security is a challenge in these networks. The scale of deployments of wireless sensor networks require careful decisions and trade-offs among various security measures Since there is an increase in possible software attacks on privacy and safety of health applications, safety and reliability of the sensor data is an important issue that needs to be addressed in this field. A unique design of a secure sensor node prototype has been proposed and implemented. In this prototype we using the PCF8591 module this is used for converting Analog to digital data for Raspberry Pi. By using this we communicate both modules as a Master and Slaves for I2C protocol. With help of I2C we can collect the data from sensors like LDR, Temperature sensors and then this data will be saved in a readable and writeable format in directory like VAR (Variable data stored by daemons and utilities) and then this data will encrypted with RC4 algorithm and similarly the encrypted data will be decrypted by RC4 algorithm by key sent by user by using HTML page from an Embedded  server that was installed in raspberry Pi both in desktop and mobile platforms the secure sensor data will be display on monitor with QT farmed environment
