Security related changes:
- Improved protection for replay attacks
- Improvement of encryption algorithm: using CCM instead of ECB
- Improvement of Session Key management
- Improved protocol downgrade protection
- Implementation of „Force 256bit mode“ so that AirID cannot be forced down to communicate with AES 128bit encryption. Force 256bit mode is enabled per default
Performance related changes:
- Reduction of power consumption
- Power down the smart card on out-of-coverage
- Have a higher connection interval when there is no BLE traffic for some time
- Correct rates in USB CCID descriptor
- Improved Android compatibility (discovering of our GATT service)
Usability related changes:
- Smart card icon on AirID display blinks when the card is powered on
- New setting menu item „USB card reader mode“ so that the USB cardreader mode can be enabled by default when USB is connected
