Initially developed to be an immutable, public, secure and distributed ledger that solves the double-spend problem of the bitcoin digital currency, the blockchain has gain the attention of the scientific community. Its disruptive nature was such that three generations of blockchains are commonly identified and referred to: Blockchain 1.0, the digital currency, Blockchain 2.0, the digital finance, and Blockchain 3.0, the smart contracts or the digital society. Smart contracts foresee the use of blockchain technologies in contexts other than currency.

On one hand, the potential use of blockchain in various sectors of the economy is becoming a reality. On the other, the development of novel technologies and services must assume a security-by-default approach. Moreover, such services may or may not have privacy requirements.

This workshop seeks submissions from academia and industry presenting novel research on theoretical and practical aspects of data protection, privacy, security, cryptography and blockchain. Papers describing the application of security technology, the implementation of systems, and lessons learned are also encouraged. Papers describing new methods or technologies, advanced prototypes, systems, tools and techniques and vision papers indicating future directions are also encouraged.


This workshop focuses on current achievements and future trends in computer and information security and in applications of blockchains focusing on the following (but not limited) topics:


  • Blockchain and authentication.
  • Blockchain and identity management.
  • Blockchain for e-Healthcare systems.
  • Blockchain for data aggregation and linkage.
  • Blockchain interoperability.
  • Benchmarks of blockchains and related technologies.
  • Use cases and implementation of blockchains.


  • Information Security
  • Computer Network Security
  • (Web) Application Security
  • Security in Middleware, Interface and Interaction
  • Authentication, Authorization, Integrity and Nonrepudiation
  • Digital Identification Management
