本文提出了一种电流平坦化系统的电路级实现，用于控制电源电流，保护密码系统免受功率分析攻击。当需要时，所提出的电路通过注入额外电流和缩放电源电压来动态控制功耗。该电路可与密码处理器集成在同一芯片上。通过这种方式，电源电流对于侧信道攻击几乎没有什么有意义的信息。所提出的电路采用0.18 μ m CMOS技术设计，并在标称1.8 v电源下工作
This paper presents the circuit-level implementation for a current flattening system designed to control the power-supply current and to protect cryptosystems from power analysis attacks. When required, the proposed circuit dynamically controls the power consumption by injecting an extra current and by scaling the power-supply voltage. The circuit can be integrated on the same chip with a cryptographic processor. In this way the power-supply current has little meaningful information for a side-channel attack. The proposed circuit has been designed in a 0.18 mum CMOS technology and operates with a nominal 1.8-V power supply
