The blockchain, originated from the Bitcoin in 2008, has shown significant potentials in achieving large-scale self-organizing in trustless distribute networks. Taking the traits of its properties, such as decentralization, autonomous, and other possible functions, it has aroused widespread interest in academia and industry all over the world. Also, its related researches and applications have been quickly extended from the original cryptocurrencies into the financial industry, the Internet of Things and the intelligent manufacturing, etc. However, with the deepening of researches, the security and privacy issues of the blockchain have gradually emerged, such as improper key management, weak anonymity and transactions information leakage.
As the security and privacy is a key evaluation parameter in the practical deployments of the blockchain platforms or the blockchain-based applications, some researches have been conducted in the area of cryptography and cryptographic techniques, which are considered as the underlying fundaments of the blockchain. However, on the one hand, there are still many cryptographic techniques that can provide desirable security properties have not been well-studied or well-applied in blockchain. On the other hand, some cryptographic primitives having been used in existing blockchain systems are high-consuming in computation or communication, which greatly impacts the usability and practicability of the blockchain. Exploring lightweight cryptographic alternatives and new promising cryptographic techniques for blockchain is still a challenging research direction.
