Android 15 set to enhance messaging security with Google Contacts managing encryption keys
With Android 15, Google is set to improve secure messaging by allowing Google Contacts to manage encryption keys. This new feature will make it easier for users to send and receive private, verified messages, ensuring a higher level of security across different apps.
In modern messaging, a system called asymmetric encryption is used. This method relies on two keys: a public key, which is available to others for encrypting messages, and a private key, which only the message recipient holds to decrypt those messages. While public keys are accessible to verify a sender’s identity, some messaging services require extra steps to find or confirm these keys, adding complexity to secure communication.
The upcoming Android 15 update, which began with its initial beta release, indicates that Google is taking steps to simplify this process. According to reports (via AssembleDebug and Android Authority), Google Contacts will now work in tandem with Play Services to manage public encryption keys. This update will streamline the verification process, ensuring more reliable identity checks and encrypted communications, removing the need for users to verify public keys on a per-app basis.
Centralized Key Management Across Apps
The system for managing and verifying public keys was first introduced in Android 15 as an API feature. It was designed to allow users to oversee their contacts’ public keys across the entire Android ecosystem rather than relying on individual apps to manage them. A teardown of the Google Play Services APK revealed that development is in progress, with new activities and features related to key management and onboarding. Users will be able to confirm a contact’s key by scanning a QR code or manually comparing code numbers across various apps.
This central verification process brings added convenience and security, as users won’t need to rely on each app’s own methods to check encryption keys. A similar feature was introduced by Apple about a year ago, which simplified key management and improved the overall security experience for its users. Apple’s centralized key verification approach showed how managing these keys within a single service could ensure smoother, safer communication.
Android’s Approach to Improving Messaging Security
While Google’s implementation is still in development and may seem basic at the moment, it promises to offer a more secure way to handle public key verification once fully rolled out. Users will benefit from the simplicity of managing encryption keys through Google Contacts, ensuring a more consistent level of security across multiple messaging apps.
Though Apple rolled out a similar feature earlier, Google’s move toward centralized key management represents a significant upgrade for Android users. As this feature evolves, it’s expected that it will further enhance both privacy and ease of use, giving users confidence in their digital communications.
By integrating encryption key management into Google Contacts, Android 15 is taking a major step toward ensuring that messages remain private and secure, making it a standout feature for future releases.
