About Silicon Labs Bluetooth
What is Bluetooth?
Bluetooth is a wireless technology standard managed by the Bluetooth Special Interest Group (SIG). Designed for data transfer and exchange over short distances, Bluetooth makes use of the unlicensed ISM band at 2.4 GHz. Bluetooth includes a number of capabilities that span point-to-point audio streaming to large scale many-to-many mesh networks for lighting or home automation.
Silicon Labs provides flexible, highly-integrated Bluetooth products that meet the most demanding requirements for a wide variety of applications. Silicon Labs engineered products for longevity and have best-in-class RF sensitivity and power consumption. In addition, Silicon Labs offers easy-to-use but powerful software solutions that can help make application development and integration a straightforward process.
Security and Bluetooth
When considering security in the context of IoT, there are multiple aspects a developer needs to consider. Very few protocols are transmitted without some form of encryption in place. The alliances behind most of the leading standards-based protocols tend to make it mandatory and most proprietary protocols tend to implement protocol security using existing well-tested industry schemes.
In all cases, however, the encryption used by the protocol is only as strong as the security offered by the physical device itself. The easiest device attack is a remote attack on software to inject malware which is why a hardware root of trust secure boot is critical. Many IoT devices are easily acquired in the supply chain and allow “Hands-On”, or “Local” attacks which allows attacking the debug port or using physical attacks like side-channel analysis to recover secrets outside of communication encryption.Silicon Labs offers a portfolio of device-level security options.
