There is plenty of on-going research in the area of supporting protocol stacks, crypt systems and formal methods. Multicast authentication is a critical security service in mobile and sensor networks. Cyber-Physical Systems [CPS] are controlled or monitored by computer-based algorithms, tightly integrated with the Internet and its users. The interaction patterns are increasingly becoming complicated. Unless, humane approaches are introduced in security engineering the computer-based approaches become increasingly sophisticated, faster, expensive and complex. These solutions are replete with several vulnerabilities leaving ample scope for breaches resulting in serious tangible and intangible losses to the organizational assets. This paper has a focus on the human integration in CPS. It also positions the analog systems in the digital space. Humane Security Engineering is intended to result in civilizing effect on people.
