"Key 1" in the message view represents the Current Key received form the PointPerfect Thing as
shown in Figure 11, and "Key 2" represents the Next Key.
For each key, the related fields should be filled in as follows:
• Encryption algorithm = 0 – AES
• Key length = 16 (Bytes)
For Key 1, the fields "Valid from WNO" and "Valid from TOW" can be filled in with the current date
expressed in GNSS data format, while for Key 2 these fields can be filled in using the Key 1 expiration
date.
As an example, consider 22 March 2022 as the current date (you could use a GNSS online data
translator, e.g., http://navigationservices.agi.com/GNSSWeb) and fill in the fields as shown below:
