A Compact Pipelined Architecture of Chaotic Logistic Map for e-Health Applications

A secure architecture of e-Health applications must be carefully approached to ensure confidentiality, integrity, and authenticity. A malicious attack or privacy breach can have serious consequences, according to the General Data Protection Regulation (GDPR). The security protocols and their cryptographic mechanisms that are commonly employed are often high resource and high execution demanding. Specifically, for the proper implementation of the key generation and the handshake protocol, various random values must be produced. This is ensured by Pseudo Random Number Generators (PRNGs) that must be compact with efficient security and verified randomness. In this paper, a compact pipelined architecture of the chaotic logistic map for e-Health applications is proposed. The proposed architecture presents a 10.82% area reduction and a 14% area delay reduction compared to other published related works. These results are achieved without the utilization of DSPs, an approach that is not followed by the other published works, while being verified by NIST tests.
