INTRODUCTION

The Information Security Group (ISG) focuses its activity on the development and proposal of security services, and their deployment in telecommunication networks.
The Information Security Group (ISG) was created at the Universitat Politecnica de Catalunya (UPC) in 2002. From the very beginning, the main strategic objective of the ISG group was to be a reference security group.
Currently, the group is formed by 9 professors and after 15 years working together, the results are 163 papers in ranked journals, 321 papers in conferences, 60 competitive projects, 20 read thesis, 17 books and book chapters, 12 awards and 9 patents.
The group is leading the security and privacy tasks in the H2020 BIG IoT project including blockchain for enhancing security and privacy on the IoT. The group has also expererience in network forensics, remote tools, cloud forensics and antiforensics tools. In addition, ISG members have worked in traceability and fingerprinting codes, as well as decoding algorithms. Finally, we have experience in authentication and certification at different protocol layers.
