椭圆曲线密码被广泛应用于便携式密码设备中,比如金融IC卡和网银USB Key等。虽然椭圆曲线密码具有很高的安全级别,但在密码设备的实现上则很容易受到侧信道攻击。国内外对ECC的侧信道分析技术的研究主要集中在发现新的攻击方法和新的防御方法上。本文综述了这些防御措施的安全性与计算效率,并基于椭圆曲线本身具有的丰富的代数特性,提出对未来研究方向的展望。
橢圓麯線密碼被廣汎應用于便攜式密碼設備中,比如金融IC卡和網銀USB Key等。雖然橢圓麯線密碼具有很高的安全級彆,但在密碼設備的實現上則很容易受到側信道攻擊。國內外對ECC的側信道分析技術的研究主要集中在髮現新的攻擊方法和新的防禦方法上。本文綜述瞭這些防禦措施的安全性與計算效率,併基于橢圓麯線本身具有的豐富的代數特性,提齣對未來研究方嚮的展望。

Elliptic curve cryptosystems (ECC) have been widely used in the portable cryptographic equipment, such as financial IC cards and USB Keys. Although the security level for the ECC is high, but in the implementation of cryptographic devices are vulnerable to side channel attacks (SCA). On the ECC side channel analysis technology research focuses on finding new methods of attacks and defenses. This paper analyzes and summarizes the security and the computation efficiency of these defensive measures, the rich algebraic properties based on elliptic curve itself has, put forward the prospects for future research directions.
