Web•Faults against RSA{CRT signatures have been an active research subject since then. Many variants and countermeasures have been proposed. •One simple countermeasure due to Shamir is to compute the signature as follows (r is a small xed integer like 231−1): 1. ˙+ p= (m)dmod r ⋅p 2. ˙+ q= (m)dmod r ⋅q 3.if ˙+ p~≡ ˙ q(mod r), abort 4. ˙=CRT(˙+ p;˙ WebJan 1, 2003 · Abstract. In this paper, some powerful fault attacks will be pointed out which can be used to factorize the RSA modulus if CRT is employed to speedup the RSA computation. These attacks are generic and can be applicable to Shamir’s countermeasure and also applicable to a recently published enhanced countermeasure (trying to improve …
WebThe public key of RSA-CRT is (e;N) and the private key includes p;q;d p;d q and i q. A fault attack is a physical attack where the attacker is able to induce faults into the execution of the algorithm. The rst attack on RSA-CRT was proposed by Bellcore researchers [5]. The fault is induced into WebRSA signature in CRT mode is described in Figure 1. Input: message m, key (p,q,dp,dq,iq) Output: signature md ∈ ZN Sp = mdp mod p Sq = mdq mod q S = Sq +q · (iq · (Sp −Sq) mod p) return (S) Fig.1.
