A Method For Point-To-Point Communications Within Secure Communication Systems Abstract of the Disclosure In a secure communication system (100), a secure point-to-point communication may be accomplished in the following manner. A first communication unit (102) receives a request from an operator for a point-to-point communication identifying at least one destination communication unit (103). In response, the first communication unit generates a private call key variable by modifying an encryption key variable through the use of a predetermined function. Identity of the encryption key variable and information pertaining to the predetermined function is transmitted by the first communication unit to the destination communication unit. Upon receiving the identity of the encryption key variable and information pertaining to the predetermined function, the destination communication unit generates the private call key variable. When the private call key variable has been determined by the first communication unit and the destination communication unit, both communication units can engage in the secure point-to-point communication.
