Ex-cop William Ryan is dismayed by his corrupt and stagnant society when Villelmus, his doppelgänger from an advanced civilisation from another universe, drops in and makes an offer he cannot refuse: join him in another realm which has evolved to the state William wishes for his own society. But there''s a catch: William must be his doppelgänger''s body double so that Villelmus can continue clandestine rescue missions to other worlds to correct the paths of those worthy civilisations which are headed for catastrophe. 

William struggles with his own ethics when he learns of these missions, but when he is thrust into new worlds his dilemma is shifted from mere contemplation to facing reality. 

Shifter: Inversion, set in a sci-fi backdrop and replete with humour, action, and intrigue is the first in the Shifter series exploring the ethical dilemma of whether it is wise to interfere with the evolution of other societies, and how much a person can change given unusual circumstances.

Cryptographic access control (CAC) is an approach to securing data by encrypting it with a key, so that only the users in possession of the correct key are able to decrypt the data and/or perform further encryptions. Applications of cryptographic access control will benefit companies, governments and the military where structured access to information is essential.

The purpose of this book is to highlight the need for adaptability in cryptographic access control schemes that are geared for dynamic environments, such as the Internet. Adaptive Cryptographic Access Control presents the challenges of designing hierarchical cryptographic key management algorithms to implement Adaptive Access Control in dynamic environments and suggest solutions that will overcome these challenges.

Adaptive Cryptographic Access Control is a cutting-edge book focusing specifically on this topic in relation to security and cryptographic access control. Both the theoretical and practical aspects and approaches of cryptographic access control are introduced in this book. Case studies and examples are provided throughout this book.
