Abstract A digital ledger which is based on distributed technology will help to

address cybersecurity and secrecy problems in the Internet of Things Architecture,

but combining these two technologies poses some difficulties. In order to preserve a

tradition of financial transactions, cryptocurrencies introduced DL technology. The

DL size in a cryptocurrency addresses hundreds of GBs, while the storage of IoT

nodes is limited. Similarly, cryptocurrencies implement costly processes of con-

sensus, while IoT nodes in calculation and energy are restricted. Moreover, clas-

sic distributed ledger technology (Bitcoin) are not based on quantum. The chapter

aims a distributed ledger security based on quantum technology, specifically dis-

tributed ledger for Internet of Things, for IoT architectures. One cornerstone of the

chapter is a new signature creation scheme which is named as Single time signature

based on time(STS), Blockchain-STS, a compact scheme. Compared with the famous

Winternitz-OTS+ system Blockchain-STS offers a 75% reduction in signature size

and a 76% reduction in signature generation time.

Introduction

IoT uses embedded technology for connecting and communicating material things.

As a massive amount of material things are interconnected, a large amount of data

is therefore generated. Maintenance of information protection and privacy remains a
