Improving the Big Mac Attack on Elliptic Curve Cryptography
At CHES 2001, Walter introduced the Big Mac attack against an implementation of rsa. It is an horizontal collision attack, based on the detection of common operands in two multiplications. The attack is very powerful since one single power trace of an exponentiation permits to recover all bits of the secret exponent. Moreover, the attack works with unknown or blinded input. The technique was la...
متن کاملBig Mac Attack: Does It Play a Direct Role for Monocytes/Macrophages in Type 1 Diabetes?
Type 1 diabetes is conventionally thought to result from T-cell–mediated autoimmune destruction of pancreatic -cells (1–3). Experimental and clinical evidence accumulated over the past two decades indicates that T-cells play a critical role in the pathogenesis of type 1 diabetes in both humans and the nonobese diabetic (NOD) mouse model of this disease (4). Indeed, the important contribution of...
متن کاملEquivalent Key Recovery Attack to H-MAC
In this paper, we propose an efficient method to break H2-MAC, by using a generalized birthday attack to recover the equivalent key, under the assumption that the underlying hash function is secure (collision resistance). We can successfully recover the equivalent key of H2-MAC in about 2n/2 on-line MAC queries and 2n/2 off-line hash computations with great probability. This attack shows that t...
متن کاملA MAC Forgery Attack on SOBER-128
SOBER-128 is a stream cipher designed by Rose and Hawkes in 2003. It can be also used for generating Message Authentication Codes (MACs) and an authenticated encryption. The developers claimed that it is difficult to forge MACs generated by both functions of SOBER128, though, the security assumption in the proposal paper is not realistic in some instances. In this paper, we examine the security...
متن کاملBig Mac parity, income, and trade
Nontraded inputs account for the lion's share of a Big Mac price (Ong 1997, Parsley and Wei 2003). Major departures from Big Mac PPP may then be explained by the Balassa−Samuelson income differences effect, as shown e.g. by Click (1996). But it has been argued that Click's result is not robust to changing estimation methods, sample of countries, and time period (Fujiki and Kitamura 2003). Here ...
