On the basis of the operation characteristics of NULL Convention Logic (NCL) circuit and popular block cipher algorithms, this paper proposes a model of NCL circuits computing, which targeted at characteristic of block cipher, and then maps rijndael algorithm on the model based on NCL circuit by two ways. The circuit model has been validated in Balsa system, and synthesized with Balsa using 1µm example NCL Cell Library. The experiment results indicate that the circuit model has high flexibility for block cipher algorithms.
