A Constant Time Full Hardware Implementation of Streamlined NTRU Prime
2021This paper presents a constant time hardware implementation of the NIST round 2 post-quantum cryptographic algorithm Streamlined NTRU Prime. We implement the entire KEM algorithm, including all steps for key generation, encapsulation and decapsulation, and all en- and decoding. We focus on optimizing the resources used, as well as applying optimization

Efficacy of constant time delay implemented by peer tutors in general education classrooms
Journal of Behavioral Education, 1994We evaluated the effects of teaching 13 typically developing children to use constant time delay when tutoring three of their peers who had substantial disabilities. We measured the extent to which the tutors used the constant time delay procedure correctly and the tutees' correct performance on the skills being taught.

Spatial Averaging Filters (SAF) are extensively used in image processing for image smoothing and denoising. Their latest implementations have already achieved constant time computational complexity regardless of kernel size. However, all the existing O(1) algorithms require additional memory for temporary data storage. In order to minimize memory usage

VLSI implementation of an efficient Fused Add-Multiply unit using Constant-time addition
2015 International Conference on Innovations in Information, Embedded and Communication Systems (ICIIECS), 2015Digital Signal Processing (DSP) applications widely use complex arithmetic operations. This paper introduces an implementation of one of the complex arithmetic operations, the Fused Add-Multiply (FAM) operation. In general, a separate adder and a multiplier are used to perform Add-Multiply operation.

On Lions and Elligators: An Efficient Constant-Time Implementation of CSIDH
2019The recently proposed CSIDH primitive is a promising candidate for post quantum static-static key exchanges with very small keys. However, until now there is only a variable-time proof-of-concept implementation by Castryck, Lange, Martindale, Panny, and Renes, recently optimized by Meyer and Reith, which can leak various information about the private ...

MemJam: A False Dependency Attack Against Constant-Time Crypto Implementations in SGX
2018Cache attacks exploit memory access patterns of cryptographic implementations. Constant-Time implementation techniques have become an indispensable tool in fighting cache timing attacks. These techniques engineer the memory accesses of cryptographic operations to follow a uniform key independent pattern. However, the constant-time behavior is dependent

We present a word- and bit-parallel magnitude-comparison architecture that permits multiple comparands to be compared with multiple relations in constant time. The proposed magnitude-comparison algorithm uses a novel polarization and wavelength-encoding scheme to achieve a fast, scalable realization.

Preservice undergraduates should acquire many skills in their teacher preparation program that support them as future effective teachers. For special education preservice teachers, one of these important skills is teaching with the constant time delay procedure, an evidence-based practice for teaching learners with moderate or severe disabilities.
