Custom digital key development solution in compliance with CCC.

From the usage of conventional turnkey systems to remote smart key fobs, lock and key systems have undergone quite an evolution.

Development has only continued. Now, a personal mobile device can act as a key, capable of not controlling vehicle access and ignition, but also enabling secured vehicle sharing among multiple users.

As the first automotive cybersecurity company in Asia to join the Car Connectivity Consortium (CCC), AUTOCRYPT provides a Digital Key development solution based on CCC Digital Key 2.0 standard, with compatibility for Release 3.0 underway.

Based on AutoCrypt® V2D, a PKI-based authentication system for vehicle-to-device communications, AUTOCRYPT’s Digital Key is secure, reliable, and convenient.

Utilizing its proprietary PKI technology, AUTOCRYPT’s Digital Key provides a level of security and privacy on par with physical turnkeys, interoperable across different smartphones and vehicles, providing a seamless driving experience for both the vehicle owner and shared users.

Use Cases

Vehicle Access Control
Remotely access and control your vehicle via the Digital Key as the owner or as a shared user, with controls to the door and trunk lock, ignition, and even sounding the horn, all through the smartphone.
Key Registration & Sharing
Register your vehicle onto the Digital Key app to activate the key. The Digital Key can be shared with multiple users, who can either log in using shared credentials or via an invite link.
Restrictions & Settings
When sharing the vehicle, the owner can configure a range of restrictions and settings such as the duration of access, permission to (un)lock, as well as maximum speed. The owner can modify permissions, opt out of sharing, or extend sharing at their discretion.

What is the Digital Key?

The Digital Key allows for a smart mobile device to take the place of a physical key. With the installation of a mobile app, the Digital Key takes on all the roles of the conventional key – (un)locking doors and turning on the ignition, plus a wide range of additional features such as key sharing.

The Digital Key is practical and convenient, as it enables the driver to access their vehicles in a seamless way, eliminating the need to carry anything other than the smartphone.

AUTOCRYPT’s Digital Key utilizes Near Field Communication (NFC), which is the same technology most notably already used for contactless payment systems. Because of the embedded NFC technology in present-day mobile devices, a digital key can be installed on virtually any smartphone.

Shareable, but Secure
As one can with a regular key, a digital key can also be sent and shared with others.

However, in order to keep the sharing process secure, the sender can select specific users to receive the key and limit their use of the key to certain functions. This shareability can contribute to the expansion of car sharing services in the era of connected and smart mobility.

Industry experts believe that the overlap between the autonomous driving industry and the carsharing/ridesharing industry is inevitable, as sharing a car is becoming much more conducive to the economical statuses of much of the population worldwide. With the Digital Key, carsharing services will become much more convenient in terms of scale and implementation. 

Market Forecast and Opportunities

The Digital Key industry is expected to reach a valuation of US$ 6 Billion by 2029, with a projected growth rate of

Significant growth is expected to show in Europe, currently the world’s largest automotive market. China and East Asia are also showing promising prospects in the Digital Key market due to high smartphone literacy. 

Standards and Compliance

The Car Connectivity Consortium (CCC), a cross-industry organization advancing smartphone-to-car connectivity solutions, releases CCC Digital Key standards for global interoperability. CCC Digital Key 2.0 uses NFC technology, while Digital Key 3.0, released in 2021, supports passive, location-aware keyless access through Bluetooth Low-Energy (BLE) in combination with Ultra-Wideband (UWB). NFC is also supported for backward compatibility.

BLE consumes very little energy, so the user can still unlock the door up to five hours after the smartphone battery reaches zero percent. UWB connectivity allows the Digital Key to control vehicles from a further point.

CCC Digital Key 1.0 : Allows smart devices to safely (un)lock vehicles

CCC Digital Key 2.0 : Incorporates standard authentication protocol, providing reinforced security and extendibility

CCC Digital Key 3.0 : Adds hands-free, location-aware keyless access, and location-aware features

Digital Key Support from Major Cellular Device Manufacturers

Major cellular device manufacturers have joined the CCC and are supporting the expanding scope of the Digital Key. While the technical details of how the devices support the Digital Key have yet to be released, it is expected that they will support vehicle access and ignition control through biometric authentication (facial and fingerprint recognition).

These operating systems are used daily by 94% of the world, this availability will contribute to a quicker expansion and adoption of the technology worldwide. 

AUTOCRYPT's Digital Key

AUTOCRYPT is the first mobility security company in Asia to join the Car Connectivity Consortium, and is working with the organization in order to conduct research, studying the level of convenience and stability of the Digital Key. 

AUTOCRYPT’s Digital Key runs on PKI-based authentication, issuing certificates that are embedded into the module during app development. Certificates are issued in conjunction with the CA (certificate authority) or the OEM’s CA, based on the policy. Manual certificate issuance is also possible by inserting a newly generated certificate into the existing module through a separate program.
