NEED OF SECURE PROTOCOL.

 

THE NEED OF SECURE PROTOCOL

Nowadays security protocols are a key component in providing security services for fixed and mobile networks. These services include data confidentiality, radio link encryption, message integrity, mobile subscriber authentication, electronic payment, certified e-mail, contract signing, and nonrepudiation

What does protocol mean?

Communication protocols are modes of communication that protect and ensure optimum security of the data being exchanged between connected devices. The IoT devices are typically connected to the Internet via an IP (Internet Protocol) network.

Why do we need a secure protocol? 

                                                 

Security protocols and encryption prevents an attacker from tapping into the air and reading data as it passes by. when it comes to the development of the IoT application, we can implement the security measures with respect to the IoT protocols to deliver secure and robust applications. This is done by taking into consideration the security requirements of these protocols, which the IoT ecosystem entirely depends on.

Organizations that are considering developing and looking to implement the IoT ecosystems, should always be up to date regarding the security basics for the IoT. As they say, to build a great structure

                                 

 Protocols in IoT

Data protocol in IoT 

IoT data protocols are used to connect low-power IoT devices. They provide communication with hardware on the user side – without the need for any internet connection.

1. MQTT (Message Queuing Telemetry Transport) 

An MQTT (Message Queuing Telemetry Transport) is a lightweight IoT data protocol. It features a publisher-subscribing messaging model and allows for simple data flow between different devices.

2. CoAP (Constrained Application Protocol)

A CoAp (Constrained Application Protocol) is an application layer protocol. It’s designed to address the needs of HTTP-based IoT systems. HTTP stands for Hypertext Transfer Protocol, and it’s the foundation of data communication for the World Wide Web.

3. AMQP (Advanced Message Queuing Protocol) 

An Advanced Message Queuing Protocol (AMQP) is an open standard application layer protocol used for transactional messages between servers.

The main functions of this IoT protocol are as follows:

• Receiving and placing messages in queues
• Storing messages
• Setting up a relationship between these components

4. DDS (Data Distribution Service)

DDS (Data Distribution Service) is another scalable IoT protocol that enables high-quality communication in IoT. Similar to the MQTT, DDS also works to a publisher-subscriber model.

5. HTTP (Hypertext Transfer Protocol)

The Hypertext Transfer Protocol (HTTP) is a networking protocol for distributed, collaborative, hypermedia information systems. As mentioned, the HTTP protocol is not preferred as an IoT standard because of its cost, battery life, huge power consumption, and weight issues.

Networking protocols IoT

IoT network protocols are used to connect devices over a network. These sets of protocols are typically used over the internet. Here are some examples of various IoT network protocols.

WiFi

There’s no denying that Wi-Fi is the most well-known IoT protocol on this list. However, it’s still worth explaining how the most popular IoT protocol works. 

In order to create a Wi-Fi network, you need a device that can send wireless signals. These include:

• Telephones
• Computers
• Routers

Bluetooth

When compared to other IoT network protocols listed here, Bluetooth tends to frequency hop and has a generally shorter range.

However, it’s gained a huge user base due to its integration into modern mobile devices – smartphones and tablets, to name a couple – as well as wearable technology, such as wireless headphones.

Mesh Protocol

A mesh usually refers to a rich interconnection network of devices that are made up of devices organized in a mesh topology Mesh topology. is a networking infrastructure in which all connected devices can cooperate to transfer and share data with each other.

LPWANs

LPWANs (Low Power Wide Area Networks) are new sets of protocols developed for IoT solutions but can also be used by other devices to communicate over a wide area. Even cellular networks can provide a wide-area communication network, but the cost of communication over cellular networks is high because of their high power consumption.
