A PKI-based track and trace network for cross-boundary container security

Challenges in container management, such as theft of products, cross-border smuggling, long checking time in processes of customs clearance and unable to track locations of products in real time, are currently faced by supply chain parties. In recent year, Electronic Seal (eSeal) technology is introduced to protect containers in a securely way. However, concerns related to data security increase when eSeal is applied in the track and trace infrastructure. To overcome this issue, this paper presents an idea to integrate the Public Key Infrastructure (PKI) in an eSeal device to enhance the cross-boundary container security.
