Smart home applications, many of which are specifically designed to monitor and record the home, need to be trusted to protect sensitive information from being exposed by illegal attacks. Every related smart device information leakage or cyber attack has damaged consumer confidence and needs to be rebuilt, while manufacturers’ reputations have also been damaged. Obviously, security is already a very important part of IoT devices! Click

IoT security is a top consumer concern
Protecting IoT devices from security threats has become a major focus for developers. This anxiety is not limited to medical devices connected to the home. Activity trackers also store, process and transmit private health data. Once leaked, users may face life danger, and in serious cases, it may even affect the reputation and business of device manufacturers. .
Enterprises, factories, manufacturers, hospitals and other public organizations also use IoT devices to run their most critical processes and assets. By
introducing
SPE
in Bluetooth
SoC
, we
have created a secure area for key storage, isolating them from components with large attack vectors, such as wireless stack, device drivers and
RTOS
, and protecting consumers, for whom security is one of the main barriers to IoT adoption.
More than
50%
of attacks on IoT devices are remote logical attacks, meaning the attacker does not have physical access to the device. These attacks include buffer overflows, code injection, and other script attacks in which attackers attempt to gain access by causing software to reveal keys.
TrustZone
creates a logical barrier within the
BG22
and
BG24
series
Bluetooth
SoCs
and modules and prevents these types of attacks by blocking direct access to critical materials. Any attempt to hack into the device will only expose the encryption key
-
preventing any intrusion and blocking future attempts.
Add a layer of security to your devices without adding complexity
The BG22
and
BG21A
parts store keys in clear text memory, while
the
BG21B
part uses
Vault
high-security key storage capabilities, or
PUF
key encapsulation, to provide an additional layer of protection
-
the more layers of protection, the more secure the device.
TrustZone
provides an easy way to add security, allowing users to store keys in secure memory or encrypted forms in non-secure memory. In addition to being able to add security to devices to differentiate them from competitors, developers can also enhance compliance with security standards, including
PSA Certified Level 2
, which requires
SPEs
to be isolated through hardware mechanisms to protect critical services and The underlying assets are not affected by non-secure handling environments.
