【摘要】:安全芯片有資源受限的問題,這致使橢圓曲線密碼算法抵抗功耗攻擊的方案在效率和安全兩方面產(chǎn)生了矛盾。首先利用帶符號的整數(shù)拆分形式對標(biāo)量進行編碼,并采用預(yù)計算和標(biāo)量分割技術(shù)把標(biāo)量乘運算變換成一組橢圓曲線上的點的點加運算,進而利用基點掩碼實現(xiàn)橢圓曲線密碼的抗功耗攻擊。算法安全性及性能分析結(jié)果表明,基于整數(shù)拆分的抗功耗攻擊方案的運算效率與傳統(tǒng)的抗功耗攻擊方法相比明顯提高,可以很好地滿足安全芯片等資源受限的應(yīng)用系統(tǒng)。
[Abstract]:The security chip has the problem of limited resources, which leads to the contradiction between the efficiency and the security of the elliptic curve cryptosystem to resist the power attack. First, the scalar is coded in the form of signed integer splitting, and the scalar multiplication is transformed into a set of point addition operations on an elliptic curve by using precomputed and scalar segmentation techniques. Then the base-point mask is used to implement the power attack of elliptic curve cipher. The results of security and performance analysis show that the computational efficiency of the scheme based on integer splitting is significantly higher than that of the traditional anti-power attack method, and it can meet the needs of resource-constrained applications such as security chips.
