Many studies have shown the weaknesses in MIFARE Classic, which is the most commonly used in access control systems, and conducted several attacks successfully. But in the situation of multi-section attacks, it would cost long time to retrieve the key of Crypto-1 cipher which is used in MIFARE Classic. We have designed a new algorithm to retrieve the key of Crypto-1 based on parallel computing using GPU so that we can reduce the time consumption for multi-section attacks. We have implemented and optimized our algorithm using CUDA and OpenCL, and tested them on different platforms contrast with the traditional method using multi-core CPU. Experimental results show that our algorithm is quite efficient on a GPU and get better performance than the traditional method on a 12-core CPU. This should be a better method to retrieve the key of Crypto-1 cipher for multi-section attacks.
