Abstract
Techniques are provided for receiving encrypted positioning assistance data, requesting and obtaining cipher keys to decrypt the positioning assistance data. An example method for transmitting a cipher key request includes receiving cipher key information including a start time value, a duration value, and an advance time value, determining an advance time duration that is equal to a sum of the start time value and the duration value minus the advance time value, and transmitting the cipher key request within the advance time duration.
