Abstract 
 In a bid to implement the Electronic Transactions Act 2015, Tanzania initiated adoption of National Public Key infrastructure (PKI) framework. However, plan has not been executed as expected because certain gaps and ambiguities in laws. This article examines existing laws providing for legal validity, admissibility enforceability electronic signatures especially using PKI; ident...

The expression and function of the endogenous inhibitor of cAMP-dependent protein kinase (PKI) in endothelial cells are unknown. In this study, overexpression of rabbit muscle PKI gene into endothelial cells inhibited the cAMP-mediated increase and exacerbated thrombin-induced decrease in endothelial barrier function. We investigated PKI expression in human pulmonary artery (HPAECs), foreskin m...

Privacy and authenticity are two essential security attributes of secure Vehicle-to-Vehicle communications. Pseudonymous Public Key Infrastructure (PPKI), an extension of standard PKI, has been proposed to achieve these security attributes. In Pseudonymous PKI, a user needs certificates or pseudonyms periodically from the Certificate Authority (CA) to authenticate messages anonymously. But the ...

The paper includes Public Key Infrastructure (PKI), its need and requirements and introduction of some renowned PKI products. However, the major thrust of this work is that how PKI can enhance security of various systems. The paper is intended to serve as a guide on how to adequately prepare for some of the challenges that may be encountered especially in developing countries like Pakistan. The...

Post-Keynesian institutionalism (PKI)—a branch of the (original) institutionalist school that builds on common ground with post-Keynesianism—constitutes a robust tradition secure foundations and broad methodological, analytical, policy contours. Since its emergence in 1980s, has consistently been ahead economic mainstream shedding light real-world problems. Drawing work various heterodox econom...

Conventional public key infrastructure (PKI) designs are not optimal and contain security flaws; there is much work underway in improving PKI. The properties given by the Bitcoin blockchain and its derivatives are a natural solution to some of the problems with PKI in particular, certificate transparency and elimination of single points of failure. Recently-proposed blockchain PKI designs are b...
