Abstract
With the advent of the Internet of Things, trust is one of the important factors for provisioning secure, reliable, seamless communications and services. Connected devices are the order of the day, where IoT plays a vital role in functioning. However, these IoT devices use various protocols for communication mostly a centralized architecture for data transfer. One of these protocols is Message Queue Telemetry Transport (MQTT), which is a Pub-Sub (publisher and subscriber) protocol used for device-to-device communication on TCP through a broker. This centralized server can be a third-party service provider, which again raises the issue of trust. To address this, we propose a decentralized and distributed network architecture called InterPlanetary File System (IPFS) is used instead of a third-party service provider. IPFS enables a publish-subscribe model similar to MQTT, but by removing the broker and making a peer-to-peer communication. Peer-to-peer architecture has its challenges like security. The issue of security is also addressed by encrypting the files or data that has to be sent over the IPFS network using PGP (Pretty Good Privacy).
Conclusion
InterPlanetary File System indeed plays a major role in the field of D2D communication. It does not only keep the data secure but also guarantees total control of the device which can be accessed from any part of the world due to its distributed architecture. The paper presents the use of IPFS in the field of the Internet of things as a communication protocol that solves the problem of data accessibility and availability by scaling out centralized servers and cloud platforms. Which makes it reliable and inexpensive for users, unlike MQTT.
