IoT secure authentication technology to prevent "spoofing" in device-to-device communication.

As smart homes and IoT services expand, the risks and concerns related to unauthorized access, impersonation, information leakage, and communication interception are also increasing, making security measures a challenge for companies deploying these services. Generally, authentication using IDs and passwords between devices can sometimes involve simple or default settings, leading to cases of falling victim to list-type attacks or brute-force attacks. "DiXiM Secure Link" introduces an authentication system that uses certificates for device pairing and further encrypts communication using those certificates, thereby preventing damage from interception, tampering, unauthorized access, and impersonation. 【Main Features】 ● Pairing Function This function allows for the pairing of two devices. Certificates are issued within the devices, and by signing and authenticating each other, communication can only occur between authenticated devices. ● Encryption Function This function encrypts communication between devices using the certificates authenticated during pairing. Encrypted communication can only be decrypted by the paired devices.

basic information

**Features** ● Pairing without using ID/PASS Unlike managing IDs and passwords, which can only be set with strings that a person can remember, the security using DiXiM Secure Link's certificates can identify several times to hundreds of times more information as identifiers, thereby increasing the security strength by several ranks. ● Add-on type security independent of data communication standards The pairing function of DiXiM Secure Link is independent of communication standards, allowing it to support various communication environments such as BLE, ZigBee, and Z-Wave. Security can be enhanced additively without changing the existing communication standards of the devices. ● Users can pair with any device Authentication using general device certificates assumes that administrators distribute certificates in advance or set up authentication, making it unsuitable for authentication between devices intended for home use or end-users. DiXiM Secure Link allows for the issuance and authentication of certificates between devices, making it suitable for pairing between any devices held by end-users.

Detailed information

**Main Features** ● Device Pairing Function Using Certificates This function allows pairing between two devices using DigiOn's unique certificates. Certificates are issued within the devices, and by signing and authenticating each other, communication can only occur between authenticated devices. ● Communication Encryption Function Using Certificates This function encrypts communication between devices using the certificates authenticated during pairing. Encrypted communication can only be decrypted by paired devices. The encryption standard complies with the NSA's Suite B.
"DiXiM Secure Link" Use Cases It is possible to enhance communication security between devices such as the following: ● Gateway device and control device ● Web camera and display device ● Smart lock and control device
