Aiming at the security and reliability of data transmission in a wireless telemetry system, a new error correcting cryptography algorithm is proposed in this paper. The novel algorithm employs quasi-cyclic low-density parity-check (QC-LDPC) codes for simultaneous encryption and channel encoding, which is different from the traditional concatenated systems where encryption and channel encoding perform serially. Thus the proposed cryptosystem exhibits attracting characteristics when it is applied to a telemetry system. The parameters are obtained according to the cryptanalysis and the corresponding key size is estimated from the compact description of the quasi-cyclic matrices. The analysis shows that the proposed error correcting cryptosystem with lower-complexity is more secure than the traditional concatenated system at a price of larger key size which is still acceptable for implementation.
