Abstract
Embodiments of the invention provide for encryption and decryption of data in a TDMA network using TDMA time values. In some embodiments, TDMA time values can be transmitted to terminals from a network controller using a burst time plan. These TDMA time values along with other data and/or counters can be combined to create a one-time key, which can be used to both encrypt data and/or decrypt data. Embodiments of the invention can decrease communication overhead by using the TDMA time value for TDMA purposes as well as for encryption purposes.
