CPA Security and Limitations
Consider Pr [ A( ,Uk,·) ( 1, E ( 1,Uk,m k )) = 1 ] for b = 0, 1 (we will refer to this as Pr [A0] and Pr [A1] for convenience). Suppose that the oracle is queried at most p (k) times for some polynomial p (k). The i-th time the oracle is queried, it picks some random c0 (call it ci,0) and then returns ci,0,Uk (ci,0) ⊕m. Let E be the event that ci,0 = c 0 for any i. Since each ci,0 is chosen at ...

متن کاملCPA beats oo-CFA
Context-sensitive points-to analysis is the current most scalable technology for constructing a precise control-flow graph for large object-oriented programs. One appealing feature of this framework is that it is parametric thus allowing to trade time for precision. Typical instances of this framework are k-CFAs and Agesen’s Cartesian Product Algorithm (CPA). It is common sense that k-CFAs (for...
متن کاملImproving Cpa Attack against Dsa and Ecdsa
In this work, we improved Correlation Power Analysis (CPA) attack against Digital Signature Algorithm (DSA) and its various derivations, such as Elliptic Curve Digital Signature Algorithm (ECDSA). The attack is aimed against integer multiplication with constant secret operand. We demonstrate this improvement on 16-bit integer multiplier in FPGA. The improvement makes it possible to guess more b...
متن کاملAnalysis Of Variance and CPA in SCA
This paper introduces Side-Channel Analysis results obtained on an unprotected circuit characterized by a surprisingly non-linear leakage. While in such a case, Correlation Power Analysis is not adapted, we show that a more generic attack, based on the Analysis Of Variance (AOV) outperfoms CPA. It has the advantage of detecting non-linear leakage, unlike Correlation Power Analysis, and of provi...
