Why Do We Need Cryptography in IoT?
IoT devices pump out large amounts of sensitive data which is not safe in this digital world. Hackers can easily steal valuable information that they shouldn’t have access to. Even worse, they might hijack these devices and use them to spread misinformation or perform malicious attacks. Cryptography can keep IoT devices and the data they transfer secure. Messages come with a special key and they can only be decoded with that particular key.
Here comes the role of encryption that significantly reduce the potential entry points for hackers that target the data between IoT devices which result application incomplete. Although most data undergoes in-transit encryption during web transmission thus centralized encryption are often lacking due to resource limitations.
Cryptography in IoT (Internet of Things)
Cryptography plays a vital role in securing information and data through the use of codes that transform the data into an unreadable format without a proper key thus preventing unauthorized access. In simple words, we can say that organizations use cryptography to secure communication channels.
