Advances in Information and Computer Security 16th International Workshop on Security, IWSEC 2021, Virtual Event, September 8–10, 2021, Proceedings

This book constitutes the refereed proceedings of the 16th International Workshop on Security, IWSEC 2021, held in Tokyo, Japan in September 2021. The conference was held virtually due to COVID-19 pandemic. The 14 regular papers and 3 short paper presented in this volume were carefully reviewed and selected from 37 submissions. They were organized in topical sections named: Lattice-Based Cryptography; System Security; Multiparty Computation; Machine Learning and Security; Post-quantum Cryptography; Symmetric-key Cryptography; Game Theory and Security.

Lattice-Based Cryptography A trace map attack against special ring-LWE samples.- Shortest Vectors in Lattices of Bai-Galbraith’s Embedding Attack on the LWR Problem.- System Security KPRM: Kernel Page Restriction Mechanism to Prevent Kernel Memory Corruption.- Evidence Collection and Preservation System with Virtual Machine Monitoring.- Multiparty Computation Evolving Homomorphic Secret Sharing for Hierarchical Access Structures.- Machine Learning and Security Understanding Update of Machine-Learning-Based Malware Detection by Clustering Changes in Feature Attributions.- Proposal of Jawi CAPTCHA Using Digraphia Feature of the Malay Language.- Solving the problem of Blockwise Isomorphism of Polynomials with Circulant matrices.- FFT Program Generation for Ring LWE-based Cryptography.- Symmetric-key Cryptography Optimum Attack on 3-Round Feistel-2 Structure.- Post-quantum Cryptography (2) An Intermediate Secret-Guessing Attack on Hash-Based Signatures.- Analysis of a Strong Fault Attack on Static/Ephemeral CSIDH.- Simple Matrix Signature Scheme.- Game Theory and Security Moving Target Defense for the CloudControl Game.
