论文摘要
在本文中，我们描述了我们在二进制扩展场GF（2L）上针对椭圆曲线的灵活ECDSA设计。我们研究了其对水平碰撞相关攻击（HCCA）的抵抗力。由于我们的设计是基于使用Lopez-Dahab投影仪的Montgomery KP算法的，因此可以使用HCCA成功地揭示了标量k，但是这种攻击可以将测量的轨迹分为与单个标量k处理相对应的部分。本文最重要的贡献是，我们的灵活场乘数是抵抗水平攻击的。这种固有的阻力使其成为设计统一的现场乘数的宝贵构件。
In this paper we describe our flexible ECDSA design for elliptic curve over binary extended fields GF(2l). We investigated its resistance against Horizontal Collision Correlation Attacks (HCCA). Due to the fact that our design is based on the Montgomery kP algorithm using Lopez-Dahab projective coordinates the scalar k cannot be successful revealed using HCCA, but this kind of attacks can be helpful to divide the measured traces into parts that correspond to processing of a single bit of the scalar k. The most important contribution of this paper is that our flexible field multiplier is resistant against horizontal attacks. This inherent resistance makes it a valuable building block for designing unified field multipliers.
