IHS Predicts IIoT Cybersecurity Will Increasingly Be Implemented in Hardware
IIoT & Cybersecurity
Although the use of secure processors in smartcard applications, such as bank cards, mobile phone SIM cards, and digital ID documents is common, IIoT developers have barely begun to adopt a hardware-enabled approach. Instead, “root of trust” technologies, such as secure key storage, cryptography, and secure boot, are handled in software on the main application processor of the device. IHS estimates that in 2015 only 9.8% of all secure processors shipped were intended for IoT applications (that is, all of IoT, not just IIoT).
The challenge with this software-based approach is that security functions on the application processor share common memory resources with other functions and are therefore exposed and vulnerable to malicious attack. Hardware isolation reduces (but cannot completely eliminate) this exposure and therefore dramatically increases the security of the device. This increased security is fundamentally why bankcards, mobile phones, and now ePassports, have shifted to the use of hardware-based security.
Chip companies such as Atmel, NXP, and Renesas Electronics have adopted this integrated approach for at least some of their respective portfolios targeting the IoT. It remains to be see whether an integrated approach will be successful. While integration helps to reduce overall device bill-of-materials, it can increase cost and complexity for cybersecurity certification, relative to a “two-chip” solution.
