IoT devices are easy targets for hacking and targeted malware. When exposed to these attacks,
IoT devices are prone to large-scale information leakage or accidents.
Weak and predictable passwords
Most IoT devices come with a password set in advance when shipped from the factory,
leaving some users easily exposed to risk as a result of default passwords.
Even if you change your password, the static code becomes easy game for hackers.
Unsecured network services
Devices connected to networks communicate continuously amongst themselves using various wireless
communication protocols. Such communication guarantees the response of IoT applications,
but if it becomes infected by malicious code or hijacked by a low-security wireless protocol, this poses real cause for concern.
Numerous IoTs, such as radio-controlled aircraft, radio-controlled cars, and industrial drones, have the potential of being hijacked. A private network can completely separate the internal network from the external, providing the most secure environment for IoT, yet it costs a fortune to build and operate such a dedicated network. A virtual private network (VPN) could be a cheaper option than a private network, but it also requires a lot of implementation and management costs so, may not be so cost efficient.
Improper data transmission
The onboard chip used for communication between the telemetry module and the unmanned device mainly uses a low-security
wireless protocol. So any sophisticated hacker who can reverse engineer the software on an unmanned device can send
navigation controls, block all commands from real operators, or even crash them.
Limitations of security/authentication solutions to IoT devices
There are many ways to defend against the increasing IoT security threats. However, most IoT devices - e.g., meters, sensors, valves, etc. - are tiny simple devices with low hardware performance, which makes it difficult to continuously operate Transport Layer Security (TLS) or Public Key Infrastructure (PKI) stack. TLS and PKI require relatively high hardware capacity because of its high memory usage, high power consumption, and heat generation of devices such as PCs and smartphones.
IoT security strategies should reduce vulnerabilities by using policies such as device identity management, encryption,
and access control. swIDch provides a safe IoT communication environment by making it near-impossible to hack and take control of
a device via a random code that changes every time in connection and commands.
- Provide unidirectional code generated by the client without communication with the server
- Generate a dynamic code that changes every time and is safe from hacking and leakage
- Block attacks in advance with one-time code that does not allow cloning and spoofing attacks
- Protect devices by issuing a unique code that never overlaps with other connected devices
- With the size of 20kB, OTAC Applet can be installed on all types of Sim cards (Classic SIM, eSIM, and iSIM)
IoT Security Platform - OTAC Applet on SIM Card
Instead of upgrading the firmware of each of numerous heterogeneous IoT device, the OTAC applet is applied to the SIM card, increasing the efficiency of integration and deployment. It can be applied to low-capacity devices that are usually difficult to continuously operate TLS or PKI stacks. In addition, it can also minimise memory usage and power consumption.
Looking at the most common configuration of IoT systems, there are two problems in Device Control & User Authentication.
- Static value or unencrypted plaintext are used in most of the command delivery.
- Without a verification process between server and device, any received information could be transmitted to the IoT device as it is, without being checked whether it is from a legitimate control server. Therefore, when command information is stolen, IoT devices can be easily controlled by unauthorized systems (hackers).
You can expect unparalleled increased security when verification is performed on SIM card with OTAC (One Time Authentication Code) Applet applied.
- When the control server sends commands to the LTE gateway, it generates and sends OTAC.
- The commands that have passed OTAC SIM verification only can be delivered to IoT devices, preventing the problem of commands being delivered to devices as they are. OTAC is valid only at 'one time' and continuously changes dynamically. Even if a hacker steals the OTAC, it cannot be reused.
Through OTAC, pilots can safely access the drone remote control system, and all commands from the remote control system and controller are converted into one-time dynamic codes sent to the drone. This makes it impossible for any external intruders to steal and control the drone as the command is no longer valid. The command converted into dynamic code reduces hijacking risks related to protocol tampering attack and replay attack to near zero.

It is possible to expand the AI speaker technology and ecosystem based on safe authentication from pairing with
