The invention discloses an information safety transmission method based on non-associative artificial noise in an untrusted relay system. The untrusted relay system comprises a sending node A, a relay node B, a receiving node C and an interference node D. The information safety transmission method is implemented in the following steps: firstly, the interference node sends artificial nose so as to interfere a signal received by the relay node B at the first stage, thereby allowing the relay node B to generate an error code platform; and on this basis, the receiving node C processes signals from two stages by use of different criterions, so interference received by the signals at the first stage is recued, and the bit error rate of the receiving node C is effectively reduced. A simulation result shows that by use of the provided three strategies, namely the zero-forcing detection, the minimum mean squared error detection and the maximum likelihood detection, the bit error rate of the receiving node C is allowed to be apparently lower than that of the untrusted relay node B. Thus, safety is ensured and the performance of the minimum mean squared error detection and the performance of the maximum likelihood detection are similar and better than that of the zero-forcing detection.
