Abstract
A wireless communications system (110) with increased privacy. The system (110) transmits an encrypted signal between a base station (112) and a wireless terminal (122). In the forward channel, the base station (112) includes an encryptor (130) with a nonlinear scrambler (202) that creates an key signal that has a nonlinear dependence on a long code mask M. The wireless terminal (122) similarly includes a decryptor (164) with a nonlinear scrambler (210) that creates a key signal that has a nonlinear dependence on the long code mask M.
