Abstract(in English) | We implemented a decryption process of AES with new bitslice technique by Kasper et al. for encryption. In conventional implementation, decryption process will take about 30% additional cycles than encryption. We present a new optimization techniq for InvMixColumns that is a part of AES decryption and implemented on Intel Core2 processor. As a result of our study we show that optimization for decryption with bitslice takes increase of about 10% over encryption. It is about 18% faster than ordinary decryption. |
