ABSTRACT:
A communication device (122) supports secure communications using automated encryption key scheduling. The communication device (122) is provided with access to one or more schedules having entries of specific time periods, such as date and time of day information, that govern selection of encryption keys. A schedule is selected and accessed using current time information to obtain an encryption key (310, 320, 330). Subsequent communications are conducted using the obtained encryption key (340).
