Secured Data Compression and Data Authentication in Internet of Thing Networks Using LZW Compression Based X.509 Certification

The Internet of Things (IoT) is a collection of physical entities that forms a huge communication between the IoT devices. The exchange of data between these IoT devices may lead to modification of data and transmission of raw data may easily prone to such modification attacks. In order to mitigate the data modification, it is necessary to compress and authenticate the raw data via devices before encrypting the data via IoT sensors to safeguard it from modification attacks. In this paper, we compress the data using LZW lossless compression scheme and then X.509 certification is used to authenticate the data using mutual authentication mechanism. The model is tested in python over a high-end computing engine, where the comparison with existing model shows that the encoded key size after compression of original data gets reduced than other methods with protection against data modification attacks.
