A secure environment is needed to communicate without any information leakage. From large devices having UPS to small devices having a battery, the parameter about security changes over time. Researchers need to work in three basics of security: (1) Mutual authentication between devices, (2) Strong encryption methodology for transmission, and (3) Secure storage environment with anytime availability. The IoT-enabled devices demand a lightweight secure environment. In this chapter, authors are concerning on all three points, i.e. Mutual authentication between devices, Strong encryption methodology for transmission, and Secure storage environment with anytime availability. Authors study some of the methods related to lightweight mutual authentication, lightweight cryptography, and local storage techniques; will talk about different issues in the field of secure communication, secure transmission, and secure storage; and will try to find out some research gap with a possible countermeasure.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
