8	Chaotic Masking
9	Chaotic Masking: Private but Secure
10	Specific Design Goals Develop one channel system Overcome security shortcomings of masking Maintain minimal degree of freedom in chaotic oscillators
11	Multiplexing Cycles Synchronization of Oscillators
12	Chaotic Multiplexing
13	Design Schematics
14	Design Schematics
15	Impediments to Hardware Implementation Parameter Matching
16	Matched Parameters
17	Parameter Mismatch
18	Impediments to Hardware Implementation
19	Software Implementation
20	Recovered Message
21	Hardware Revisited Sensitivity to Parameter Mismatch Implies Strong Tendency to Reject Improper Password Future Project: DSP + Parameter Matching
22	Conclusions Multiplexing obscures the state space Forecasting will be less effective The system offers increased security Oscillators are low order Requires a single channel Parameter Mismatch
