OCPP security certification

The full OCPP protocol certification includes many features, and the OCPP protocol security certification is one of them. It significantly enhances the security of electric vehicle charging networks through various mechanisms, ensuring reliable communication between charging stations and management systems while preventing potential cyberattacks. Currently, many charging stations on the market have OCPP protocol certification that does not include security certification. However, Huizhi Technology’s OCPP protocol 4G gateway has successfully passed the security certification from the perspective of customer security. Below are the main benefits of OCPP security certification in enhancing security:

▶ 1. Encrypted Communication to Prevent Data Leaks

The OCPP protocol uses Transport Layer Security (TLS) to encrypt communication between charging stations and Central Management Systems (CSMS), ensuring that data is not intercepted by third parties during transmission. This encryption mechanism effectively protects sensitive information such as user identities, payment data, and charging session details, preventing unauthorized access.

▶ 2. Mutual Authentication to Prevent Spoofing Attacks

OCPP security certification requires mutual authentication between the charging station and the server. By using digital certificates, the charging station can verify that it is communicating with a legitimate server, and the server can also verify that the connected charging station is a genuine and untampered device. This mechanism effectively prevents spoofing attacks, where attackers attempt to simulate fake charging stations to send false data to the server.

▶ 3. Prevention of Man-in-the-Middle Attacks

The OCPP protocol prevents man-in-the-middle (MITM) attacks by using secure WebSocket (WSS) encrypted channels. These types of attacks usually occur when communication links are interrupted or hijacked, with attackers trying to intercept or tamper with data. By combining encryption and authentication, OCPP ensures that both parties can securely exchange information without interference from malicious third parties.

▶ 4. Security Profiles for Different Levels of Protection

OCPP defines three security profiles that provide different levels of security:

  • Security Profile 1: Basic level, using password authentication.
  • Security Profile 2: Intermediate level, using TLS encryption and server certificates for authentication.
  • Security Profile 3: Advanced level, using TLS encryption and mutual certificate authentication (both client and server must provide certificates).

Most devices with OCPP certification implement at least Security Profile 2 or higher to ensure that communication channels are strongly protected.

▶ 5. Prevention of Common Cyberattack Scenarios

OCPP security certification can effectively address various common cyberattack scenarios, such as:

  • Charging Station Spoofing: Fake charging stations may send false data to the management system. Through mutual authentication mechanisms, the management system can distinguish between real and fake devices, preventing database contamination.
  • Communication Hijacking: If unencrypted communication is hijacked, attackers may intercept or modify data. OCPP prevents this type of attack through encryption and authentication mechanisms.

▶ 6. Secure Updates and Remote Management

OCPP also supports remote management functions, including remote firmware updates and system status monitoring. This allows operators to promptly fix vulnerabilities and keep systems up-to-date, reducing potential risks caused by unpatched vulnerabilities.

▶ Summary

By implementing multi-layered security measures within the OCPP protocol—such as encryption, mutual authentication, and defenses against common cyberattack scenarios—OCPP security certification provides strong protection for electric vehicle charging networks. This not only enhances overall system stability but also increases user trust in charging infrastructure, positioning it as a key player in the rapidly growing EV market.
