Symmetric Ciphers and Asymmetric Ciphers Based on Magic Cube with 6-D

The present book is considered as a guide for researchers academic scholars postgraduate students and designers of cryptographic systems. It offers an overview for the designing approaches and gives a good insight towards the building of new modern secure cryptographic protocols. It opens the door for researchers how to build a trusted and integrated system. This book has several unique features and submits a set new practical cryptographic algorithms that fit to a real world applications and daily usages that spread widely. Most of these ciphers can be considered as a standard or de facto ciphers that designed to withstand against the advance of technology development and to face the real security threats in addition to satisfy the current and perspective of future needs. This edition is supported with several branches and coverage topics that contain: -Cryptographic foundations: Security principles and comprehensions. -Magic squares and magic cube concepts techniques and methodologies. -Development of a new symmetric algorithms with modern strategies and new asymmetric ciphers based on magic square and magic cube mathematical problems in addition to the signature schemes.
