Digital Key is presented as a revolutionary technology that will change the connected car world. But will it really replace traditional keys and provide sufficient security for the end-users?
Digital Key is a technology that allows using smart devices, for example, smartphones, as keys. The main driving force for using smart devices as keys is the convenience of the car owner or user.
No, Digital Key technology is not limited to any specific industry and can be implemented in hotels, real estate, and other fields. But it is true that today automotive companies are most interested in the benefits of this technology and are driving digital vehicle key development in the search of growth opportunities.
Now, while the technology’s still in the initial phase, it’s not going to completely replace traditional keys. Its main goal is to increase convenience for the consumer.
The Car Connectivity Consortium and its members base their work on standardization of the Digital Key on such technologies as NFC, GSMA, GlobalPlatform. The solution will also be able to support future standards once they’re available.
It is expected that consumer devices holding a Digital Key will have security mechanisms to prevent such threats as:
In addition to this, security architecture must enable the receiver of the messages between a device with Digital Key, vehicle, another device, and a remote backend to verify their trustworthiness. Devices holding Digital Key are also supposed to have a hardware-based trusted execution environment as well as an operating system security framework that allows the limitation of the access to security services.
