Abstract Chaos shift keying secure communication system with dual-ring erbium-doped fiber laser is presented. The chaos shift keying is realized by modulating parameters of the pump light. A matching method to reduce the synchronization error by modulating the parameters to compensate the system parameter mismatches is numerically studied. Chaotic synchronizations and decoding at "0" and "1" bit, respectively, are numerically simulated between two single-ring erbium-doped fiber lasers and a dual-ring single-mode erbium-doped fiber lasers. The system shows the good ability of robust security and anti-uncoverage in phase-space, time-domain and frequency-domain.
