As the first official published commercial block cipher standard of China, SMS4 has been widely used in local area wireless product. Although the algorithm is proved to be secure enough mathematically, when implemented in hardware, it is vulnerable to differential power analysis (DPA), especially using chosen plaintext method. In order to discuss countermeasures against DPA, we present a secure circuit...
Recently, passive information leakage and active fault injection are widely utilized to conduct attacks and these attacks have become a serious threat to most cryptosystems such as RSA. In order to ensure the security, many exponentiation algorithms with resistance to different side-channel attacks were developed. In 2007, Amiel et al. Firstly combined Fault Attack (FA) and Simple Power Analysis (SPA)...
In this paper, we propose a hybrid power model that includes the power consumption of not only the registers but also part of the combinational logic. By doing knownkey analysis with this hybrid model, power side-channel leakage caused by correct keys can be detected. In experiment, PRINTcipher and DES algorithms were chosen as analysis targets and combinational logic s-box unit was selected to build...
SMS4 is the first official released commercial cryptographic algorithm. It provides unified standards for designing and using local area wireless network product. The general DPA attack is not suitable for SMS4 owing to the ample random diffusion of the round output. This article proposed a new power analysis method for SMS4 to reduce the diffusion by chosen plaintext. Two means - Hamming distance...
PRINT cipher is a lightweight block ciphers dedicated to integrated circuit (IC) printing, proposed by Lars Knudsen et al. at CHES 2010. Interestingly, PRINT cipher discards the key schedule part and keeps all its round keys identical. This unconventional design guarantees its modest space requirement. In this paper, however, we will show how to make use of its identical round key to mount a terrifically...
In this paper we discuss correlation power analysis attack against stream cipher MICKEY v2. In such attacks, we use Hamming-Distance model to simulate the power consumption. Hamming-Distance model is a more accurate description to power consumption than other models such as Hamming-Weight, bit model etc. Generally, Hamming-Distance model is used to map the transitions that occur at the cells' outputs...
