In this paper, a partitioned coupling analysis system is developed for a numerical simulation of 3-dimensional fluid–structure interaction (FSI) problems, adopting an incompressible smoothed particle hydrodynamics (SPH) method for fluid dynamics involving free surface flow and the finite element method (FEM) for structural dynamics. A coupling analysis of a particle-based method and a grid-based method has been investigated. However, most of these are developed as a function-specific application software, and therefore lack versatility. Hence, to save cost in software development and maintenance, the open source software is utilized. Especially, a general-purpose finite element analysis system, named ADVENTURE, and a general-purpose coupling analysis platform, named REVOCAP_Coupler, are employed. Moreover, techniques of an interface marker on fluid–structure boundaries and a dummy mesh for fluid analysis domain are adopted to solve the problem that the REVOCAP_Coupler performs to unify two or more grid-based method codes. To verify a developed system, the dam break problem with an elastic obstacle is demonstrated, and the result is compared with the results calculated by the other methods.

In order to test the security of cryptographic devices against Side Channel Attacks (SCA), an automatic general-purpose power analysis system (TH-PAS-01) is designed and implemented. TH-PAS-01 is scalable and can be applied to many cryptographic devices when specific modules are installed. Using the system TH-PAS-01, correlation power analysis (CPA) are carried out on an AES chip under two working models: normal and shuffling mode. The security level of the countermeasure provided by the target chip is verified by TH-PAS-01. The experimental results show that the correct key of the AES chip is obtained with around 50,000 power traces when the chip was working under normal mode, while the whole key bits are not obtained with 960,000 power traces when the chip works under shuffling mode. The automatic general-purpose system TH-PAS-01 is feasible for security analysis on power analysis for cryptographic devices.
