An essential element for building mobility security infrastructure based on international standards, including V2X, drone, and IoT communication link security

SAESOL Tech’s Secure Link is a mobility station security service for secure session establishment and authentication between trusted devices.

It provides security services needed to authenticate sources between devices that make up mobility systems, and to ensure confidentiality and integrity of application activities, delivering strong link security.

It supports security services using certificates issued by a trusted CA and valid certificates.

International standard support
Communication channel protection using TLS
Interoperability assurance
Access control support

Key Functions

V2X message security

Signature on transmitted V2X messages, and signature/authorization verification for received messages

Communication link security

Session management such as Secure Session connect/disconnect using ITS certificates (based on IEEE 1609.2)
Data transmission/reception via Secure Session

Certificate management

Issuance/renewal management of certificates required for ITS security on devices

Why, S2X Secure Link

Optimization for real-time communication

Millisecond-level response times are required for V2V/V2I; provides lightweight authentication and session establishment protocols for ITS environments

Automated authentication and connection

When manual authentication is impossible, automatic device-to-device authentication is essential; designed so devices can authenticate themselves and establish secure sessions

Suitable for distributed environments

ITS is an environment where many vehicles, sensors, and infrastructure communicate simultaneously; X.509-based VPNs have limits in scalability and flexibility due to centralized structures

Compatibility with autonomous driving and smart city technologies

When considering integration with smart city and traffic infrastructure, an international-standard-based security system is required

S2X Secure Link: ISO 21177 Configuration


SSProxy Server	Applied to C-ITS service networks to relay and protect incoming external traffic Operates like a security gateway, ensuring safe V2X communication flows
SSProxy Agent	Installed on devices to support TLS-based link encryption Establishes a secure channel between devices and infrastructure to ensure data integrity and confidentiality Provided in library or gateway form
Admin Console	Provides an interface to monitor and manage agent status and certificate validity in real time Improves operational convenience and control for security administrators
