The threat of side‐channel attacks poses a significant risk to the security of cryptographic algorithms. To counter this threat, we have designed an AES system capable of defending against such attacks, supporting AES‐128, AES‐192, and AES‐256 encryption standards. In our system, the CPU oversees the AES hardware via the AHB bus and employs true random number generation to provide secure random inputs for computations. The hardware implementation of the AES S‐box utilizes complex domain inversion techniques, while intermediate data is shielded using full‐time masking. Furthermore, the system incorporates double‐path error detection mechanisms to thwart fault propagation. Our results demonstrate that the system effectively conceals key power information, providing robust resistance against CPA attacks, and is capable of detecting injected faults, thereby mitigating fault‐based attacks.

A U-shaped hollow-fiber membrane of A-site deficient K 2 NiF 4+δ -type oxide (Pr 0.9 La 0.1 ) 1.9 (Ni 0.74 Cu 0.21 Ga 0.05 )O 4+δ ((PL) 1.9 NCG) was developed through the phase inversion spinning method. At 975 °C, 2.51 mL/min cm 2 oxygen permeation flux can be achieved under air/He. And stable oxygen permeation performances were obtained during the 285 h long-term tests. The electrical conductivity, surface morphology and oxygen permeation properties of (PL) 1.9 NCG hollow-fiber membrane were studied in detail. [ABSTRACT FROM AUTHOR]

A novel concept for the preparation of multiphase composite ceramics based on demixing of a single ceramic precursor has been developed and used for the synthesis of a dual-phase H2-permeable ceramic membrane. The precursor BaCe0.5Fe0.5O3− δ decomposes on calcination at 1370 °C for 10 h into two thermodynamically stable oxides with perovskite structures: the cerium-rich oxide BaCe0.85Fe0.15O3− δ (BCF8515) and the iron-rich oxide BaCe0.15Fe0.85O3− δ (BCF1585), 50 mol % each. In the resulting dual-phase material, the orthorhombic perovskite BCF8515 acts as the main proton conductor and the cubic perovskite BCF1585 as the main electron conductor. The dual-phase membrane shows an extremely high H2 permeation flux of 0.76 mL min−1 cm−2 at 950 °C with 1.0 mm thickness. This auto-demixing concept should be applicable to the synthesis of other ionic-electronic conducting ceramics. [ABSTRACT FROM AUTHOR]
