A novel modular exponent randomizing method is proposed to resist side-channel attack in RSA cryptosystem. The limitation of this method is given and the way of using random values also brings the security benefits. Experimental results show that though the randomized exponentiation sequence can be analyzed, the real private key is still covered. At last, the attack cost for this randomized sequence...
Power analysis attack has been widely used against cryptographic devices such as smart cards. Compared to the origin differential power analysis (DPA) attack, the later developed correlation power analysis (CPA) is advantageous due to its robustness and efficiency. However, the existing CPA power models are defective in principle as they are either based on a power model using Hamming weight or simplified...
Power analysis attacks as side channel analysis techniques of cryptographic devices have been mounted against block ciphers and public key but rarely against stream ciphers. There are no reports on correlation power analysis (CPA) attack against stream ciphers so far. This paper proposes a novel CPA against synchronous stream ciphers. Then we present two experiments of CPA attacks on stream ciphers...
Authentication and encryption technology are the core components of the DRM (Digital Rights Management) system. In this paper, a security protocol basing on the identity-based signcryption scheme is proposed to implement these technologies simultaneously. According to the comparison with the PKI (public key infrastructure)-based DRM system, the advantages of this protocol are proved. However, in practice...
To improve the DPA resistance of cryptographic device in intellectual cards, a power analysis platform is constructed for AES. After analyzed the AES encrypt process, a MASK circuit, disturbance circuit for clock and disturbance circuit for power are designed and implemented in an AES coprocessor of ZTEIC Corporation's intellectual card. The AES coprocessor can process data with 900 Mbps at 100 MHz...
This paper describes the design and implementation of an ultra low power RSA coprocessor. By improving the Montgomery's algorithm, and using several low power techniques on the design of the RSA coprocessor, this paper has designed a RSA coprocessor with ultra low power consumption and high performance. The RSA coprocessor is implemented using TSMC 0.18 um CMOS technology in one of the ZTEIC Corporation's...
