Cryptographic algorithm detection has received a lot of attentions in these days, whereas the method to detect decrypted data remains further research. A decrypted memory detection method using dynamic dataflow analysis is proposed in this paper. Based on the intuition that decrypted data is generated in the cryptographic function and the unique feature of decrypted data, by analyzing the parameter sets of cryptographic function, we propose a model based on the input and output of cryptographic function. Experimental results demonstrate that our approach can effectively detect decrypted memory.
