How to Secure IoT Devices with PKI as a Service
Read time: 6 minutes
PKI for IoT Security
Security Conditions for IoT
- The authenticity of devices is a must before deployment. Protecting the integrity and confidentiality of data collected, stored, or transmitted by the apparatus is necessary.
- They must also validate each device by providing digital signatures and certificates.
- It should meet the industry compliance needs.
Securing IoT devices with PKI
- By using Asymmetric encryption
By using asymmetric encryption, we can provide the essential methods for strong cryptographic encryption and ensure private communication. It ensures that all the certificates issued are from the single certificate authority, which is trusted.
- Establish and Defining Security Standards
Various standards provided by PKI provide you the comfort of defining a system cryptographically, with various options for revocation, renewal, and standard protocols for enrollment of certificates like EST REST API.
- Maintaining Stronger Security
Talking about digital certificates provided by maintained PKI provides far more safety than traditional means of authentication. With the help of PKI, we have authentication and encryption capability, which helps us maintain robust Security.
- By using unique identities
Using individual identities for every device, you can enable secure network access and code execution throughout the device’s existence. Also, these certificates can be updated as per needs.
Advantages of PKI for IoT
Encryption
- We can provide the essential methods for strong cryptographic encryption and ensure private communication by using encryption.
- Encryption helps in providing support for various IoT devices.
- Provides robust encryption for data at rest and data in transit.
Authentication
- Provides secure authentication without using a password between devices.
- Establishes trust among devices and users.
Integrity
- Data Integrity ensures that the data transmitted hasn't been altered in any way.
- Digitally signing papers, emails, and other data provides authorization and digital integrity.
Challenges
- Everything can’t be done with traditional PKI Infrastructure, as traditional PKI Infrastructure is built to work without constraints, and in case of conditions, problems may occur.
- Scalability for PKI might become an issue, i.e., building IoT-focused Certificate Authority is required.
- Since IoT has various devices, traditional PKI Implementation may face issues in issuing certificates and implementing Security in IoT.
