SSE Implementation of Multivariate PKCs on Modern x86 CPUspared to “traditional” alternatives. However, this advantage seems to erode with the increase of arithmetic resources in modern CPUs and improved algorithms, especially with respect to Elliptic Curve Cryptography (ECC). In this paper, we show that . Modern commodity CPUs also have many small integer

Physical Unclonable Functions and Secure Processorsed and unsupervised. On the other hand, the cost of security breaches is increasing as we place more responsibility on the devices that surround us. The result of these trends is that physical attacks present an increasing risk that must be dealt with..Physical Unclonable Functions (PUFs) are a tamp

Practical Electromagnetic Template Attack on HMACistance of some registers. After a . in which the adversary has access to a device and can configure it, the attack recovers the secret key by monitoring a . of HMAC-SHA-1. The secret key can be recovered using a “template attack” with a computation of about 2. 3. compression functions, where . is t

First-Order Side-Channel Attacks on the Permutation Tables Countermeasureng that during the execution of an algorithm, each intermediate variable that is handled is in a permuted form described by the random permutation tables. In this paper, we examine the application of this countermeasure to the AES algorithm as described in [5], and show that certain operations admit

A New Side-Channel Attack on RSA Prime Generationion that allows to determine the number of the trial divisions for each prime candidate. Practical experiments are conducted, and countermeasures are proposed. For realistic parameters the success probability of our attack is in the order of 10–15 %.
