Universal Digital Key Standard 'Aliro' Launches
A new universal digital key framework called Aliro has launched to standardize secure access across smart locks, cars, and buildings. Nelson Henry of the Connectivity Standards Alliance says the goal is to make digital keys as simple and secure as physical ones, but far more flexible.
The Aliro 1.0 specification has officially launched, marking a significant step towards a universal standard for digital keys. Spearheaded by the Connectivity Standards Alliance (CSA), the same body behind the Matter smart home protocol, Aliro aims to eliminate the fragmentation in the access control market. The initiative, in development since 2021, seeks to replace proprietary systems with a single, interoperable framework. Over 220 member companies, including tech giants Apple, Google, and Samsung, are backing Aliro. These companies have committed to integrating Aliro into their mobile wallet ecosystems, allowing users to store and use digital keys on their smartphones and wearables without needing multiple manufacturer-specific apps. This broad support is designed to ensure that digital keys become as seamless and ubiquitous as contactless payments. The standard utilizes a combination of Near Field Communication (NFC), Bluetooth Low Energy (BLE), and Ultra-Wideband (UWB) technologies. This multi-technology approach enables various access methods, from a simple tap-to-unlock with NFC to hands-free, proximity-based entry using UWB, which also helps prevent relay attacks. Aliro is designed to function even in offline environments like underground garages. Security is a core component of the Aliro standard, which employs asymmetric cryptography to secure interactions between devices and access readers. The security model is comparable to the bank-grade cryptography used for tap-to-pay services, using public and private keys stored securely on the user's device. While the Aliro 1.0 specification is now available for manufacturers, widespread consumer availability is expected to follow later in 2026 as companies build support and get their products certified. Several companies, including Aqara, Nuki, Assa Abloy, and Kwikset, are already preparing for Aliro certification, with some products like the Aqara Smart Lock U400 and the Nuki Smart Lock Pro (4th-gen) announced with Aliro in mind.
