In recent years, the Internet of things has become a topic of interest and speculation for most technology enthusiasts, specifically its tenuous relationship with security. But smart card applications used intelligently can provide greater security for IoT devices.
IoT provides the framework that allows better integration between the physical world and electronic devices over existing networks, which makes these devices smarter.
IoT-enabled devices can be seen not only in industries such as manufacturing, construction, logistics and agriculture, but also in smart homes and smart cars. Gartner estimates that 20 billion dedicated functional devices will be connected online by 2020.
Most of the speculation about IoT has focused on the safety of these devices. Since they are connected through existing networks, IoT devices are vulnerable to attacks by hackers and other criminals in society.

Smart cards as security measures
Smart cards have been used for a long time to secure different types of human network transactions. For example, they are used to make secure payments for purchases through the bank's payment network.
Smart card access control allows employers to grant specific and controlled access to buildings and facilities. They can also be combined with other forms of authentication techniques such as pins, passwords and biometric data to implement a stronger authentication protocol.
the safe microcontroller Inside a smart card, also known as smart chip, it allows you to store and process data and carry secure communication with smart card readers. Let us now see how the security mechanisms provided by the intelligent could be integrated into the IoT systems to secure them.
the Secure Technology Alliance recommends The use of integrated hardware security for IoT devices. This would require that untouchable security components and encryption capabilities be integrated directly into IoT devices at the manufacturing stage.

The built-in technology can be used to protect the identity of the devices and prevent unauthorized manipulation.
This integrated security could be provided by smart chips that would protect the privacy and security of the devices, as well as the large amount of data generated by the devices.
The chips would not only control how the devices would work under normal conditions, but also how they would react when they were manipulated or attacked in some way.
The need to secure IoT devices has also led to the manufacture of special chips called safe items. A secure element is a microprocessor chip that can store, process and protect that in a trusted environment isolated on a connected device.
They can store cryptographic keys and improve memory security. They also offer an environment resistant to cryptographic data manipulation. Several secure elements with improved interface logic can be integrated into IoT devices and connected industrial equipment to offer digital security at the smart card level.
Secure items help ensure that access is granted only to authorized applications and people.
Smart cards can also be used to log in the user on the IoT server. The server would authenticate the user and generate a unique session key that will allow the user to safely use the connected IoT devices.
Smart cards can also help in the management of encryption keys between the card, the user and the device. This will ensure the confidentiality and integrity of the sensitive information that is transmitted.
In conclusion, IoT devices must be protected by design rather than security being a late occurrence. Enhanced smart chips or secure elements can be integrated into the IoT device to authenticate devices and applications, just as smart cards are used to authenticate people.
Smart cards can also be used to authenticate users and administrators of IoT devices. Therefore, smart card technology can be used to ensure both device-to-device interactions and device-to-human interactions.
