Bluetooth is a technology for wireless communication between two devices in a short distance (up to 15 m). It is based on communication between two paired devices for secure authentication. It is possible to use this technology instead of RFID cards. This identification is provided by a unique code of the end-devices that contains this technology, like almost every smartphone these days. There is a direct communication between a smartphone and 2N IP Intercom or 2N Access Unit equipped with Bluetooth module. This communication is secured and based on public and private keys that are exchanged (we use RSA-1028 asymmetric encryption and AES-128 symmetric encryption).
If you paired your smartphones by the offline method (not via My2N management platform), we recommended to change the Encryption Keys for Location every 3 months in order to keep a high level of security. If you are using the on-line method via My2N management platform, then the Encryption Keys are changed automatically.
Prerequisites
- 2N IP Intercom or 2N Access Unit equipped with Bluetooth module,
we suggest to use the latest firmware, no additional license is required. - Smartphone with enabled Bluetooth and My2N app
paired with 2N IP Intercom or 2N Access Unit by the offline method according to this instructions:
Bluetooth Tap in App Mode - how to setup My2n App and use the feature
Changing the Encryption Keys for Location
- Go to 2N device web interface, section Services - Access Control - WaveKey,
and generate the new Encryption Key.
- Both the old one and the new one will be available simultaneously, so all authorized apps (which can open doors on that device) will be able to exchange the previous key for new one.
It is recommended to keep the old key in device for a few days, till all mobile apps exchange the stored key to match the new one. Each app will do it automatically once it is in close proximity of 2N device with updated location authentication key.
After you delete old key, apps which did not get in proximity of 2N device in time will lose their ability to open these doors and mobile phone needs to be paired with 2N device device again.
