Abstract Blockchain of Things (BCoT), as a new paradigm that incorporates blockchain with
the Internet of Things (IoT), can address the privacy and extensibility issues in IoT systems …

The concept of verifiable delay functions has received attention from researchers since it
was first proposed in 2018. The applications of verifiable delay are also widespread in …

Timed-release encryption (TRE) makes it possible to send messages “into the future” such
that a pre-determined amount of time needs to pass before a message can be accessed …

This paper introduces the notion of timed secret sharing (TSS), which establishes lower and
upper time bounds for secret reconstruction in a threshold secret sharing scheme. Such time …

Time-lock puzzles (TLP) are a cryptographic tool that allow one to encrypt a message into
the future, for a predetermined amount of time T. At present, we have only two constructions …

To securely transmit sensitive information into the future, Time-Lock Puzzles (TLPs) have
been developed. Their applications include scheduled payments, timed commitments, e …

Time-Lock Puzzles (TLPs) are cryptographic protocols that enable a client to lock a message
in such a way that a server can only unlock it after a specific time period. However, existing …

Fair exchange protocols let two mutually distrustful parties exchange digital data in a way
that neither party can cheat. They have various applications such as the exchange of digital …

Timed data delivery is a critical service for time-sensitive applications that allows a sender to
deliver data to a recipient, but only be accessible at a specific future time. This service is …

A verifiable timed signature (VTS) scheme allows a signature to be time-locked to a known
message for a predetermined duration denoted as. Verifiability ensures that anyone can …
