Limitations of Cryptography in IoT
- Encrypted key loss: One challenge with encryption lies in managing the encryption keys. Losing a private key can render the corresponding data inaccessible even to owner also. This highlights the importance to secure key by preventing it from permanent data loss.
- Complexity: Securing and restoring encrypted data in IoT environments presents a significant challenge due to the complexity of the process as we use symmetrical key encryption and with this the chances of attack are higher.Alternative to this is using asymmetrical encryption where data can be prevented but complexity increases.
- Maintenance: It requires high expenses to upgrade and maintain the system.
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.
