Why Is Code Signing Necessary for IoT Devices?
To protect businesses, brands, partners, and users from software that has been infected by malware, software developers have adopted code signing. In the IoT, code signing in the software release process ensures the integrity of IoT device software and firmware updates, and defends against the risks associated with code tampering or code that deviates from organizational policies.
In public key cryptography, code signing is a specific use of certificate-based digital signatures that enables an organization to verify the identity of the software publisher and certify the software has not been changed since it was published.
