Customized firmware allows differentiated algorithms for each application. The communication
chain is fully secured using classic techniques such as:
 Authentication: secured passwords or signed tokens
 Encryption: AES-128
When implementing on GPIO that are enabled by the target microcontroller’s debug protocol,
data encryption is enabled to the level of the TapNLink module.
When implementing with S3P protocol, security features can be implemented on the target
microcontroller. Features include data encryption and filtering of accessible addresses in the
target’s memory space.
