Abstract

Timed release of confidential information, where information is revealed at the date and time established by the author, is a security requirement in applications such as auctions, wills, and government buying processes. We have found that this security requirement is achieved through the fulfillment of a group of requirements that are not completely understood. We propose the development of an infrastructure that enables the fulfillment of the studied security requirements. The infrastructure, Temporal Key Release Infrastructure (TKRI), was developed as a proof of concept. We also discuss the advantages of our approach against other proposals. 1
