Generating trust in IoT devices is getting easier and effective with improved embedded security capabilities.
FREMONT, CA: The deployment of IoT devices has ushered in operational efficiency for numerous industries today. However, the beneficiaries are also plagued by the prospects of privacy and security attacks. To protect the value of IoT devices, security measures are important. Security measures, which are as innovative as the technology of IoT, can contribute towards maintaining the integrity of systems. This is where embedded security can step in and make a lot of difference. By enabling in-built security features within IoT devices, embedded security can protect extensive systems from vulnerabilities. Some ways in which embedded security is helping IoT systems overcome security limitations are enlisted below.
Protection for Embedded Memory
Embedded security involving a Memory Protection Unit ( MPU) can add a layer of protection to the embedded memory and protect it from being accessed on the occasion of an attack. Security management units in the ICs can also offer substantial degrees of protection to IoT devices. With flexible and granular protection for embedded memory, the confidentiality of data can be maintained.
Embedded security within IoT devices allows for hardware-enabled encryptions. Encryption is vital for protecting data present in the system from being accessed by intruders. With built-in hardware modules, IoT devices are equipped to generate security keys and achieve cryptographic capabilities. Such in-built encryptions are very advantageous from the perspective of IoT devices.
Enabling Root of Trust (RoT)
Sometimes corrupt software applications result in the compromise of IoT device security. By embedding RoT capabilities into the hardware, it is possible to execute security checks within isolated hardware components. Built-in RoT not only secures the software implementation but also helps in reducing the cost of IoT device security.
Today, advancements in embedded technology have given a boost to the prospects of securing critical IoT devices. Embedded security allows effective countermeasures and technologically superior safeguards, which ensure that every IoT device is protected.
