Saha-Edge’s edge-AI enables real-time offline secure credential provisioning and lifecycle management for smart tokens without cloud connectivity, maintaining compliance with ISO/IEC 15118-2 and zero-trust charging protocols through local cryptographic operations and secure token storage.
How Saha-Edge ensures secure offline operations
Saha-Edge leverages local edge computing to perform cryptographic functions directly on the charging station. This includes generating and validating secure tokens, managing their lifecycle, and enforcing zero-trust principles without requiring constant cloud communication. The system stores credentials in tamper-resistant secure elements, ensuring that even if the device is offline, it can still authenticate users and manage access.
This approach is particularly valuable in remote or low-connectivity environments where network reliability is a concern. It allows charging stations to operate autonomously while maintaining the same level of security and compliance as cloud-connected systems.
Practical implications for fleet and enterprise operators
Fleet operators benefit significantly from this capability, as it allows them to deploy charging infrastructure in locations with limited or unreliable internet access. The system ensures that vehicles can be charged without interruption, even during network outages or in areas with poor connectivity.
For enterprise deployments, Saha-Edge’s offline functionality reduces dependency on centralized systems and enhances operational resilience. It supports scenarios where immediate access control and secure credential management are critical, such as in industrial or commercial settings with strict security requirements.
