Nowadays, security becomes a great concern, as the devices start to process more and more sensitive data, leading to an increased number of attacks. The nodes in an wireless sensors network usually collect environment-related and then send the data to a gateway, in order to be processed. There might be cases when the collected information leaks sensitive user data, so encrypting the communication would be a good practice is this cases. This project proposes and implements a method of securing the radio communication using symmetric cryptography on Sparrow v4 nodes.
