Side-channel attacks (SCAs) exploit leakage from the physical implementation of cryptographic algorithms to recover the otherwise secret information. In the last decade, popular SCAs like differential power analysis (DPA) and correlation power analysis (CPA) have been invented and demonstrated to be realistic threats to many critical embedded systems.(More)

Semicompeting risks data are commonly seen in biomedical applications in which a terminal event censors a non-terminal event. Possible dependent censoring complicates statistical analysis. We consider regression analysis based on a non-terminal event, say disease progression, which is subject to censoring by death.The methodology proposed is developed for(More)
A popular effective countermeasure to protect block cipher implementations against differential power analysis (DPA) attacks is to mask the internal operations of the cryptographic algorithm with random numbers. While the masking technique resists against first-order (univariate) DPA attacks, higher-order (multivariate) attacks were able to break masked(More)
The TVLA procedure using the t-test has become a popular leakage detection method. To protect against environmental fluctuation in laboratory measurements, we propose a paired t-test to improve the standard procedure. We take advantage of statistical matched-pairs design to remove the environmental noise effect in leakage detection. Higher order leakage(More)
Keccak is the hash function selected by NIST as the new SHA-3 standard. Keccak is built on Sponge construction and it provides a new MAC function called MAC-Keccak. These new algorithms have raised questions with regards to side-channel leakage and analysis attacks of MAC-Keccak. So far there exists prior work on attacks of software implementations of(More)
A protection circuit can be added into cryptographic systems to detect both soft errors and injected faults required by Differential Fault Analysis (DFA) attacks. While such protection can improve the reliability of the target devices significantly and counteract DFA, they will also incur extra power consumption and other resource overhead. In this paper,(More)
Feature selection aims to select relevant features to improve the performance of predictors. Many feature selection methods depend on the choice of dependence measures. To select features that have complex nonlinear relationships with the response variable, the dependence measure should be equitable; i.e., it should treat linear and nonlinear relationships(More)
As Keccak has been selected as the new SHA-3 standard, Message Authentication Code (MAC) (MAC-Keccak) using a secret key will be widely used for integrity checking and authenticity assurance. Recent works have shown the feasibility of side-channel attacks against software implementations of MAC-Keccak to retrieve the key, with the security assessment of(More)
