Tecell’s platform enforces secure communication between chargers and the CMS using TLS 1.3 encryption by default, ensuring all data exchanged is protected against eavesdropping and tampering. The system automatically negotiates the strongest available TLS version, rejects older insecure protocols, and validates certificates through trusted authorities. All connections are monitored for compliance, and any failed handshake attempts are logged for security review.
How TLS 1.3 is Implemented in Practice
In real-world deployments, Tecell’s CMS acts as the TLS server, while chargers connect as clients. The platform configures each charger to only accept TLS 1.3 connections, rejecting any attempt to use older protocols like TLS 1.0 or 1.1. This ensures that even if a charger is compromised, attackers cannot downgrade the connection to a weaker encryption method.
Each charger is provisioned with a unique certificate that is validated against a trusted certificate authority. If a certificate is expired or invalid, the connection is denied immediately, preventing unauthorized access to the charging network. This process happens automatically during the initial handshake, without requiring manual intervention.
Why This Matters for Charge Point Operators
For operators managing large fleets of chargers, TLS 1.3 provides a robust defense against man-in-the-middle attacks and data breaches. It ensures that sensitive information like payment details, user identities, and charging session logs remain confidential and intact. This is especially important when deploying chargers in public spaces or shared environments.
Operators also benefit from Tecell’s automated compliance monitoring, which flags any connection attempts that do not meet TLS 1.3 standards. This helps maintain consistent security across all devices, even when new chargers are added to the network over time.
