Cybersecurity comapny Intercede this week announced bitcoin security products provider Ledger has signed up to use its MyTAM service to protect its apps running on Android, according to a press release.

Intercede said by securing the wallets with the secure Trusted Execution Environment already present on many leading devices, the app, along with data and transactions made by it, is protected against threats that may be present on the handset.

The TEE, developed by Trustonic, is a cryptographically locked, secure operating environment built into leading Android devices at the point of manufacture. By protecting bitcoin wallets with this trusted environment, the application and related transactions are protected from malware, man-in-the-browser and other forms of software-based threats that are potentially active on devices, according to the announcement.

Ledger provides hardware security solutions for innovative decentralised trust services — its first product, Ledger Nano, a USB smartcard-based hardware bitcoin wallet, is used by thousands of customers in over 60 countries, according to the announcement. By adopting Intercede's MyTAM service, Ledger provides a downloadable, secure and flexible hardware bitcoin wallet to protect users against fraud and malware attacks.

Intercede said its MyTAM service is currently used by companies supplying apps and development toolkits across a range of sectors that require access to complete end-to-end security facilities for Android apps, including e-commerce wallets, secure voice provision and enterprise-strength messaging.

"Intercede is leading the way in offering the strongest security available on Android for bitcoin wallet providers," Intercede CEO Richard Parris said in a statement. "By using MyTAM to securely load its apps in the TEE, Ledger joins the growing number of high-profile app providers using the strongest level of Android security to protect their apps and end-users' digital assets."
