An efficient construction of key-dependent substitution box based on chaotic sine map
International Journal of Distributed Sensor Networks, 2019 A substitution box is a core component of the popular symmetric-key algorithms. However, the major problem of the conventional substitution boxes is the statistic behavior, which is employed as a fixed-size lookup table.

Mom-and-Pop Meet Big Box: Complements or Substitutes? [PDF]
SSRN Electronic Journal, 2009 Abstract In part due to the popular perception that Big-Boxes displace smaller, often family owned (a.k.a. Mom-and-Pop) retail establishments, several empirical studies have examined the evidence on how Big-Boxes’ impact local retail employment but no clear consensus has emerged.

Pitfalls in Designing Substitution Boxes [PDF]
, 2007 Two significant recent advances in cryptanalysis, namely the differential attack put forward by Biham and Shamir [3] and the linear attack by Matsui [7, 8], have had devastating impact on data encryption algorithms. An eminent problem that researchers are facing is to design S-boxes or substitution boxes so that an encryption algorithm that employs the
