A Preliminary Design for Authenticity of IoT Big Data in Cloud Computing

The cloud computing, as a more distributed and more efficient paradigm with better performance, has played an important role in many fields. The cloud environment under the IoT has also assumed many roles such as the storage, the processor, the service provider and so on. However, the complex deployment and usage environment of the IoT brings new security risks to cloud computing. In response to this situation, this poster preliminarily designed a security scheme for the cloud environment of IoT. Based on the identity verification algorithms and blockchain technology, the credibility of data stored in the cloud can be ensured, while the security of data transmission from the cloud to data consumers is achieved.
