Nowadays, Internet of Things (IoT) is gradually finding its way, into everybody's life. This paper, introduces both the design and the implementation of a privacy framework, for the Internet of Things (IoT). Taking the benefits from it, a privacy platform is developed with a twofold aim: firstly, to train in detail the fundamentals of cryptography and privacy, and secondly, to make applied cryptography more interactive and flexible. Through this work, the proposed architecture and the integration of this open platform is presented, in detail. In addition, an application of symmetric cryptography is introduced, based on the Advanced Encryption Standard(AES) in various modes of operation, for both encryption and decryption of texts, images and electronic data files.
