DR.SGX: Automated and adjustable side-channel protection for SGX using data location randomization
(2019)Proceedings of the 35th Annual Computer Security Applications Conference (ACSAC '19)Recent research has demonstrated that Intel's SGX is vulnerable to software-based side-channel attacks. In a common attack, the adversary monitors CPU caches to infer secret-dependent data accesses patterns. Known defenses have major limitations, as they require either error-prone developer assistance, incur extremely high runtime overhead, or prevent only specific attacks. In this paper, we propose data location randomization as a ...Conference Paper -

Analyzing students’ mental models of technical systems
(2019)2019 IEEE 17th International Conference on Industrial Informatics (INDIN)Successful innovation processes require communication between different disciplines, such as mechanical and electrical engineering or software development. However, such communication is hampered by differences in individual mental models. This paper presents two studies that investigate mental models of engineering students. The studies apply SA/RT and card sorting to analyze mental models and were conducted at the beginning of their ...Conference Paper -
A Calibration Procedure for Sand Plasticity Modeling in Earthquake Engineering: Application to TA-GER, UBCSAND and PM4SAND
(2019)Proceedings in Earth and Geosciences ~ Earthquake Geotechnical Engineering for Protection and Development of Environment and ConstructionsA generalized element-test based calibration methodology is developed. The calibration is based on best matching the response in terms of (a) the liquefaction resistance (CRR) curve as a function of the relative density of sand and the equivalent number of uniform cycles required to trigger liquefaction, and (b) experimentally derived shear modulus and damping ratio curves commonly used in practice. Regarding the first part of the calibration ...Conference Paper -
Pile-Soil Kinematic Interaction considering Soil Nonlinearity and Group Effects
(2019)Proceedings in Earth and Geosciences ~ Earthquake Geotechnical Engineering for Protection and Development of Environment and ConstructionsThe results from a thorough finite element analysis with code PLAXIS are presented in which both the piles and the soil are modeled in 3D with volume elements. A suitable plasticity model is employed for treating the nonlinear soil behaviour in cyclic loading after appropriate calibration of its parameters to match published relationships of shear modulus and damping ratio curves. The influence of key-model parameters, such as: (a) strong ...Conference Paper -
Seismic effective stress analysis of caisson–type quay walls: A comparative study between constitutive models
(2019)Proceedings in Earth and Geosciences ~ Earthquake Geotechnical Engineering for Protection and Development of Environment and ConstructionsA well-documented case history of a wharf liquefaction-induced failure from Kobe 1995 earthquake is employed for checking the reliability of two widely-applied in practice constitutive soil models. More specifically, the seismic response of the quay wall RC-5 in Rokko island is reproduced by conducting both undrained and uncoupled—consolidation-based—effective stress analysis with the finite element code PLAXIS using the UBC-Sand and ...Conference Paper -
