Perforation-based computational tools refer to a category of computational techniques and technologies that make use of "perforation" as a foundational concept. While the term might vary in meaning depending on the specific domain, it generally relates to methods that involve creating holes, gaps, or segments within a material or data set to achieve certain functionalities or efficiencies.
An edge-notched card is a type of punch card that is used for data storage and processing. It typically has one or more notches or indentations along the edges, which are used to represent information or data. The notches are read by machines or devices that can detect the presence or absence of notches at specific positions, allowing for a binary representation of data.
Grille is a lightweight cryptographic algorithm designed for applications requiring efficient encryption and decryption processes, particularly in environments with limited resources such as Internet of Things (IoT) devices. It was designed by a team led by Thomas Peyrin in 2018 and is notable for its balanced approach, offering both security and performance. The algorithm operates on a block structure, processing data in fixed-size blocks, and utilizes a combination of substitution and permutation operations to achieve confidentiality.
