News Release: Texas Instruments and ARM Accelerate Deployment of Secure Applications on Mobile Devices
M-Shield Hardware Security Technology
Integrated into TI's OMAP and OMAP-Vox platforms, M-Shield hardware security technology is a complete infrastructure for mobile platform robustness that includes:
- Hardware cryptographic accelerators and randon number generator
- Public key infrastructure with secure on-chip keys (e-fuse)
- Secure booting and flashing
- Secure access/restriction to all chip peripherals and memories
- Secure DMA transfers
- Hardware-based countermeasures against software attacks and cloning
- Secure protection of debug, trace, and test capabilities
- Hardware-reinforced secure execution and storage environment (Secure Environment) embedding:
- A Secure State Machine
- Secure RAM for sensitive authorized application execution and secure data storage
- Secure ROM with 100+ accessible by authorized applications (Protected Applications)
- Secure storage mechanism
M-Shield hardware security technology is operating system-independent and not sensitive to software attacks. And once it is available, ARM® TrustZone™ hardware extensions will be incorporated and strengthened.
M-Shield Software Security Technology
M-shield software security technology is the key software-based security element of OMAP Platforms and OMAP-Vox devices, built on top of and strengthened by M-Shield Hardware technology. This software security encompasses:
- Secure signing and flashing tools
- IMEI and SIMlock protection software on OMAP-Vox devices
- Toolkits for development and signature of protected applications running in a secure environment
- Security Middleware Component with associated Protected Applications and SDKs
- Security packs to strengthen HLOS security
Additionally, the M-shield Security Middleware Component (SMC) provides sets of standard APIs that solve the problems of de-fragmentation and porting complexity:
- Software reuse across platform generations as APIs on current platforms can continue to be utilized
- SMC APIs are compatible with ARM® TrustZone™ software APIs
- Applications can call specific secure services ported on SMC using ARM TrustZone API
- Applications can use secure storage and standard PKCS#11 APIs for cryptography
- Native secure services can use standard PKCS#11 APIs
- Interpreted secure services can use GlobalPlatform GPD/STIP mobile profile standard APIs
- Applications developed on TI's M-shield mobile security technology today will run binary compatible on devices incorporating an ARM core with TrustZone hardware extensions
- Services developed today using ARM TrustZone software API will run on TI devices with M-Shield mobile security technology
