With the growing number of internet connected devices, concerns have arisen about their security and privacy. The lack of proper security measures on these devices has led to a number of high-profile cyber attacks, which have resulted in data breaches and other significant consequences. In response to these concerns, the European Telecommunications Standards Institute (ETSI) has developed a new standard called ETSI EN303 645.

What does the standard cover?

ETSI EN 303 645 is a comprehensive standard that outlines specific cybersecurity requirements for consumer IoT devices. Here are some detailed aspects of the standard:

  1. Identification and authentication:
    • Devices must support secure and unique identification.
    • Authentication mechanisms should be robust and resistant to common attacks.
  2. Secure boot and secure updates:
    • Devices must have a secure boot process to ensure only trusted software runs.
    • Software updates must be authenticated and integrity-checked to prevent unauthorized modifications.
  3. Data protection:
    • Sensitive data, both in transit and at rest, must be encrypted using strong cryptographic methods.
    • Access to sensitive data should be restricted to authorized entities only.
  4. User privacy:
    • Devices must provide clear information about data collection, processing, and sharing practices.
    • Users should have control over their data, including the ability to request deletion.
  5. Lifecycle management:
    • Manufacturers must provide ongoing support for security updates throughout the device’s lifecycle.
    • Devices should have a clear end-of-life process to ensure they do not become security risks.
  6. Secure defaults and configuration:
    • Devices should ship with secure default settings.
    • Users should be able to easily configure security settings.
  7. Transparency and information for users:
    • Manufacturers must provide clear and accessible information about security features and how to use them.
    • Users should be informed about potential security risks and how to mitigate them.
  8. Resistance to common attacks:
    • Devices must be designed to resist common types of cyberattacks, such as denial-of-service, man-in-the-middle, and replay attacks.

By adhering to these specific requirements, manufacturers can ensure that their consumer IoT devices are more secure and better protect users’ privacy and data.

Who does it apply to?

The standard applies to manufacturers of IoT devices that are sold or used in Europe. It also applies to anyone who uses these devices, including consumers and businesses.

What impact will the standard have on the IoT industry?

It will help to ensure that IoT devices are more secure and reliable, which can improve their performance and increase consumer trust. However, it may also lead to increased costs for manufacturers, which could make some devices more expensive.


The ETSI EN303 645 standard is an important step forward in ensuring the security and privacy of IoT devices. While there are challenges involved in implementing the standard, its benefits are clear. As the IoT industry continues to grow, it is essential that we take steps to ensure that these devices are secure and reliable. The ETSI EN303 645 standard is a positive step in that direction.
