SAESOL Tech S2X CMS

S2X CMS is a PKI-based Security Credential Management System (SCMS) that issues and manages large-scale security certificates for mobility communication environments, including V2X, EV charging payment, and drone security authentication. The system is compatible with IEEE 1609.2-2022 for issuing Enrollment Certificates and Authorization Certificates used for secure message signing, and supports the IEEE 1609.2.1-2022 API for functions such as downloading the trusted root Certificate Trust List (CTL), certificate chain (CCF), and Certificate Revocation List (CRL), as well as enrollment/authorization certificate requests and misbehavior reporting. It supports both the newer IEEE 1609.2.1 standard and the legacy CAMP standard within a single SCMS, allowing continued support for older CAMP-based devices alongside newer deployments. The platform includes an operations system for viewing certificate issuance status by device, configuring global or device-level policies, and managing CA certificates (issuance, CSR generation, revocation, renewal). S2X CMS is built for cloud-native deployment on AWS, Azure, Naver Cloud, and G-Cloud, with support for DevOps/CD pipelines and Docker-based container deployment. It is designed for high availability with load balancing, automatic backup, an in-memory database, and auto-scaling. Device credential validation uses Canonical ID and ISO 21177 (RFC 8902). The product includes logging and auditing capabilities along with notification integrations for Slack, Microsoft Teams, and KakaoTalk. The company reports listing in the Production CTL of the North American SCMS Manager, registration in China's TRCL (Root CA Trust List), registration in Europe's ECTL Level 0, and partial completion of ECTL Level 1, along with GS Certification Level 1.
