To fulfill the Chinese government?s targets for energy conservation and emission reductions, significant efforts to increase efficiency and reduce emissions in the energy system have been made by developing combined heat and power plants, expanding transmission, and incorporating renewables. These elements are not always compatible with each other, however. Renewables in particular face difficulties...
In this paper, we use advanced multi-agent technologies to establish a smart power grid to solve the power distribution restoration problems. Specifically, we modeled switches in the power distribution systems as intelligent agents who can communicate and coordinate together to find a global optimal solution to the power distribution service restoration problems. We modeled the society of intelligent...
Establishing a smart power grid utilizing advanced agent information technology has raised much attention recently. In this paper we propose a method that is based on coordination and negotiation among a set of distributed local power committees who could together reach a consensus of “global” optimal power restoration solution in cope with local power failures after a fault is detected in a power...
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...
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...
