2016 Proceedings of the 2016 ACM SIGSAC Conference on Computer and Communications Security - CCS'16  
An effective countermeasure against DPA is to mask secrets by probabilistically encoding them over a set of shares, and to run masked algorithms that compute on these encodings.  ...  Our methodology relies on several contributions of independent interest, including a stronger notion of probing security that supports compositional reasoning, and a type system for enforcing an expressive  ...  Acknowledgements The work presented here was supported by projects S2013/ICE-2731 N-GREENS Software-CM, ANR-10-SEGI-015 PRINCE and ANR-14-CE28-0015 BRUTUS, and ONR Grants N000141210914 and N000141512750  ...

Noise reduction in the recording of holographic masks in photoresist

Lucila H. D. Cescato, Leandro L. Soares, Elso L. Rigon, Marco A. Alves, Edmundo S. Braga, Sing H. Lee, J. Allen Cox
1999 Micromachine Technology for Diffractive and Holographic Optics  
In this paper we study the effect of the mask profile and of the phase perturbations during the holographic exposure in the noise of the photoresist masks.  ...  It is shown that the use of appropriate conditions of development and exposure may reduce significantly this noise allowing the recording of high aspect ratio structures and the use of selective deposition  ...  This type of response is more suitable for the recording of holograms4 where several interference patterns are superimposed. For lithography, however, a high non-linear response is more desired.  ...

We also consider three-beam interference effects, a consequence of the zeroth-order component present in addition to higher-order diffraction components.  ...  The masks are used to produce fibre Bragg gratings having different orders according to the phase mask period.  ...  One does need to account for the effect of the non-zero contribution of the strong zeroth-order component that is present in the transmission characteristics of the mask and that modifies the ideal, anticipated  ...

Proposal of Plane-Parallel Resonator Configuration for High-NA EUV Lithography [article]

Tsumoru Shintake
2022 arXiv   pre-print
EUV light is injected through an off-axis rotating mirror at the back focal plane and provides off-axis illumination (precession beam) to the mask and bounces back twice (at the mask and the wafer), finally  ...  Plane-parallel resonator configuration is proposed for high-NA EUV lithography, where the lithography mask and the wafer are parallelly arranged through two focusing mirrors.  ...  Truncating beam at any aperture will cause strong interference pattern on the projected image on the wafer, which overlaps with the mask pattern.  ...

Consolidating Security Notions in Hardware Masking

Lauren De Meyer, Begül Bilgin, Oscar Reparaz
2019 Transactions on Cryptographic Hardware and Embedded Systems  
We show that this single condition includes, but is not limited to, previous security notions such as those used in higher-order threshold implementations and in abstractions using ideal gates.  ...  We also treat the notion of (strong) noninterference from an information-theoretic point-of-view in order to unify the different security concepts and pave the way to the verification of composability  ...  The ease of verification comes at the cost of higher implementation and randomness cost since the demands for strong non-interference are quite high.  ...
