AUSTIN, Texas, March 5, 2020 /PRNewswire/ -- Silicon Labs (NASDAQ: SLAB) announces Secure Vault technology, a new suite of state-of-the-art security features designed to help connected device manufacturers address escalating Internet of Things (IoT) security threats and regulatory pressures. Silicon Labs' Wireless Gecko Series 2 platform takes advantage of Secure Vault by combining best-in-class security software features with physically unclonable function (PUF) hardware technology to greatly reduce the risk of IoT security breaches and compromised intellectual property.
"The security landscape is changing rapidly, and IoT developers face increasing pressure to step up device security and meet evolving regulatory requirements," said Matt Johnson, senior vice president and general manager of IoT product at Silicon Labs. "Secure Vault simplifies development, accelerates time-to-market and helps device makers future-proof products by taking advantage of the most advanced integrated hardware and software security protection available today for IoT wireless SoCs."
Secure Vault's hardware features provide an optimized level of security implemented in a cost-effective, wireless SoC solution. The security subsystem, including a dedicated core, bus and memory, is separate from the host processor. This unique design of hardware separation isolates critical features, such as secure key store management and cryptography, into their own functional areas, making the overall device more secure. The new combination of security features is ideal for companies working to address emerging regulatory measures, such as GDPR in Europe and SB-327 in California.
"Embedded security is a key requirement for IoT products, and software updates alone cannot address all vulnerabilities present in insecure hardware," said Tanner Johnson, senior cybersecurity analyst at Omdia. "As a result, hardware components can comprise the front line of defense for device security, especially with new legislation targeting IoT product security."
Secure Vault advances IoT security through a unique combination of hardware and software features that make it easier for product manufacturers to protect their brand, design and consumer data. Integrating a security system with a wireless SoC helps designers simplify development and makes it possible to securely update connected devices over-the-air (OTA) throughout the product lifecycle. The delivery of genuine, trusted software or firmware to connected products serves to mitigate unforeseen exploits, threats and regulatory measures.
Secure Vault delivers new security features including:
Secure Device Identity One of the biggest challenges for connected devices is post-deployment authentication. Silicon Labs' factory trust provisioning service with optional secure programming provides a secure device identity certificate during IC manufacturing, analogous to a birth certificate, for each individual silicon die, enabling post-deployment security, authenticity and attestation-based health checks. The device certificate guarantees the authenticity of the chip for its lifetime.
Secure Key Management and Storage The effectiveness of a security scheme for device and data access directly depends on key secrecy. With Secure Vault, keys are encrypted and isolated from the application code. Virtually unlimited secure key storage is offered as all keys are encrypted using a master encryption key generated using a PUF. The power-up signatures are unique to a single device, and master keys are created during the power-up phase to eliminate master key storage, further reducing attack vectors.
Advanced Tamper Detection This feature offers a wide range of capabilities from easy-to-implement product enclosure tamper resistance to sophisticated tamper detection of silicon through voltage, frequency and temperature manipulations. Hackers use these changes to force hardware or software to behave unexpectedly, creating vulnerabilities for glitch attacks. Configurable tamper-response features enable developers to set up appropriate response actions with interrupts, resets, or in extreme cases, secret key deletion.
Pricing and Availability Silicon Labs is currently sampling new Secure Vault-enabled wireless SoCs, which are planned to be released in late Q2 2020. For additional information on Silicon Labs' security technologies, visit silabs.com/security.
