Abstract
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.
