Advantages of Cryptography in IoT
- Security: Cryptography ensures security by encrypting the data and this make it unreadable to unauthorized person. Layer of protection on data is been added. We can think of it as an financial transaction that is need to be secure and safe.
- Integration of data: To ensure that data reaches to right person and that too without any changes is critical concern in IoT. Cryptography plays a vital role in addressing this challenge as it arrive wuth techniques such as digital signature and message authentication codes to prevent data integration during transmission.
- Authentication of the user: Proper user or device authentication is important in IoT to prevent unauthorized access and safeguard sensitive data. Malicious attacks can exploit and steal information. This is evident in smart home system where authentication ensures only to authorized individuals like homeowner, as he/she can unlock the door using fingerprints or password scanners.
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.
