SAN JOSE, Calif., Oct. 10, 2018 (GLOBE NEWSWIRE) -- (ARMTECHCON2018) -- Delivering on the vision to secure IoT edge devices, and cloud to edge connections, NXP Semiconductors N.V. (NASDAQ:NXPI) combines hardened security subsystems and software into a secure execution environment (SEE) to raise the bar on trust, privacy, and confidentiality. The new security functionalities and capabilities are key highlights in its new Cortex-M33 based solutions, LPC5500 microcontrollers and i.MX RT600 crossover processors.
Multi-Layered Approach to Embedded Systems Security
Building on the company's security expertise, NXP brings multi-layered, hardware-enabled protection scheme that is unique in the industry today. Vital to physical and run-time protection, this layered security approach protects embedded systems with:
- Secure boot for hardware-based immutable root-of-trust
- Certificate-based secure debug authentication
- Encrypted on-chip firmware storage with real-time, latency-free decryption
These features in conjunction with Arm® Cortex-M33 enhancements of Arm TrustZone® technology for Armv8-M architecture and Memory Protection Unit (MPU), ensures physical and runtime protection with hardware-based, memory mapped isolation for privilege-based access to resources and data.
"The promise of the connected world through the Internet-of-Things is extraordinary," said Geoff Lees, senior vice president and general manager of microcontrollers at NXP. "Through NXP's in-depth security and processing expertise, software ecosystem and breadth of portfolio, we are uniquely positioned to bring innovative and accessible advancements in IoT security to all developers."
Unique Security Enhancements
A cornerstone to establishing device trustworthiness is NXP's ROM-based secure boot process that utilizes device-unique keys to create an immutable hardware ‘root-of-trust'. The keys can now be locally generated on-demand by an SRAM-based Physically Unclonable Function (PUF) that uses natural variations intrinsic to the SRAM bitcells. This permits closed loop transactions between the end-user and the original equipment manufacturer (OEM), thus allowing the elimination of third-party key handling in potentially insecure environments. Optionally, keys can be injected through a traditional fuse-based methodology.
Furthermore, NXP's SEE improves the symmetric and asymmetric cryptography for edge-to-edge, and cloud-to-edge communication by generating device-unique secret keys through innovative usage of the SRAM PUF. The security for public key infrastructure (PKI) or asymmetric encryption is enhanced through the Device Identity Composition Engine (DICE) security standard as defined by the Trusted Computing Group (TCG). SRAM PUF ensures confidentiality of the Unique Device Secret (UDS) as required by DICE. The newly announced solutions support acceleration for asymmetric cryptography (RSA 1024 to 4096-bit lengths, ECC), plus up to 256-bit symmetric encryption and hashing (AES-256 and SHA2-256) with MbedTLS optimized library.
"Maintaining the explosive growth of connected devices requires increased user trust in those devices," said John Ronco, vice president and general manager, Embedded and Automotive Line of Business, Arm. "NXP's commitment to securing connected devices is evident in its new Cortex-M33 based products built on the proven secure foundation of TrustZone technology, while incorporating design principles from Arm's Platform Security Architecture (PSA) and pushing the boundaries of Cortex-M performance efficiency."
Accelerating Machine Learning and DSP Compute Performance
NXP strategically selected Cortex-M33 to leverage the first full-feature implementation of Armv8-M architecture to provide security platform benefits and substantial performance improvements compared to existing Cortex-M3/M0 MCUs (over 15 to 65 percent improvement, respectively). One of the key features of the Cortex-M33 is the dedicated co-processor interface that extends the processing capability of the CPU by allowing efficient integration of tightly-coupled co-processors while maintaining full ecosystem and toolchain compatibility. NXP has utilized this capability to implement a co-processor for accelerating key ML and DSP functions, such as, convolution, correlation, matrix operations, transfer functions, and filtering; enhancing performance by as much as 10x compared to executing on Cortex-M33. The co-processor further leverages the popular CMSIS-DSP library calls (API) to simplify customer code portability.
LPC5500 Platform – Multi-core Cortex-M33 MCUs for Industrial and IoT Applications
Single- or Dual-core Cortex-M33 with integrated DC-DC delivers industry-leading performance at a fraction of power budget, of up to 90 CoreMarks™/mA. The high density of on-chip memory, up to 640KB flash and 320KB SRAM, enables efficient execution of complex edge applications. Further, NXP's autonomous, programmable logic unit for offloading and execution of user-defined tasks delivers enhanced real-time parallelism.
