AES-128 Performance in Tinyos with CBC Algorithm (WSN)

The wireless sensor network (WSN) is a combination of sensing, computation, and communication into a single tiny device known as Sensor nodes. Sensor data is shared between these sensor nodes and used as input to a distributed estimation system. The wireless network environment that consists of the many devices, called the sensor node, which have miniature computing device, small memory space and very limited battery power. Therefore, Symmetric key encryption algorithm with low-Energy consumption is required to the applicable sensor networks. In this paper, we proposed the solution of reliable sensor networks to analyze the communication efficiency through measuring performance of AES-128 CBC algorithm which is selected by default in sensor networks by plaintext size and cost of operation per hop according to the network scale. In this work, both encryption and decryption will be carried out with the key length of 128 bits, that is, both AES encrypter and the AES decrypter were integrated. Hence the input block and secret key will be provided for encryption and the cipher block and same secret key will be provided to the decryption to get the proper block as output.
