Google has announced Adiantum, a new form of encryption designed for lower-end devices that do not come with specialized hardware to keep them secure.
This new encryption will make more devices secure, specifically lower-end devices that did not benefit from this type of encryption previously.
Adiantum is a new form of encryption that we built specifically to run on phones and smart devices that don’t have the specialized hardware to use current methods to encrypt locally stored data efficiently. Adiantum is designed to run efficiently without that specialized hardware. This will make the next generation of devices more secure than their predecessors, and allow the next billion people coming online for the first time to do so safely. Adiantum will help secure our connected world by allowing everything from smart watches to internet-connected medical devices to encrypt sensitive data.
Why Adiantum is Important
The introduction of Adiantum is a significant step forward in the realm of digital security. Traditionally, encryption methods have relied heavily on specialized hardware, such as the Advanced Encryption Standard (AES), which is efficient but requires specific hardware support to run effectively. This has left many lower-end devices, which lack such hardware, vulnerable to security threats. Adiantum addresses this gap by providing a robust encryption solution that does not depend on specialized hardware, making it accessible to a broader range of devices.
For instance, many affordable smartphones, smartwatches, and IoT (Internet of Things) devices have been unable to implement strong encryption due to hardware limitations. With Adiantum, these devices can now encrypt sensitive data efficiently, enhancing the overall security landscape. This is particularly crucial as the number of connected devices continues to grow, with estimates suggesting that there will be over 75 billion IoT devices by 2025.
Technical Aspects of Adiantum
Adiantum is based on the ChaCha stream cipher, which is known for its speed and security. The ChaCha cipher is combined with the XChaCha12 variant, which extends the nonce size, making it more secure against certain types of attacks. This combination allows Adiantum to provide strong encryption without the need for hardware acceleration.
One of the key advantages of Adiantum is its efficiency. It is designed to run on devices with limited processing power, ensuring that encryption does not significantly impact device performance. This is achieved through a series of optimizations that reduce the computational overhead associated with encryption.
Moreover, Adiantum is designed to be flexible and adaptable. It can be implemented on a wide range of devices, from low-cost smartphones to medical devices and smart home gadgets. This versatility makes it an ideal solution for securing the next generation of connected devices.
Adiantum will help secure our connected world by allowing everything from smartwatches to internet-connected medical devices to encrypt sensitive data.
