Ateniese, Di Pietro, Mancini, and Tsudik win the 2020 Jean-Claude Laprie Award

May 21, 2020

Today, IFIP Working Group 10.4 announced that an outstanding paper has been selected as winner of the 2020 Jean-Claude Laprie Award in Dependable Computing:

  • Ateniese, G., Di Pietro, R., Mancini, L. V., Tsudik, G. Scalable and Efficient Provable Data Possession.
    In Proc. 4th Intl. Conf. on Security and Privacy in Communication Networks (SecureComm), Istanbul, Turkey
    (September 2008), Art. No.9, pp.1-10,

The Award Citation:
“Scalable and Efficient Provable Data Possession” by Giuseppe Ateniese, Roberto Di Pietro, Luigi V. Mancini, and
Gene Tsudik established the basis for provable data possession based on highly-efficient symmetric key cryptography.
The paper was seminal in allowing the outsourcing of dynamic data, i.e., by efficiently handling operations such as
block modification, deletion, and append. This is the first solution to provide these properties and is still unsurpassed.
The paper had a considerable impact on the field. In addition to the academic impact (1300+ citations), the proposed
PDP method is at the core of the many solutions that remotely check data consistency (e.g., distributed databases, online
social networks, remote data backup), and is finding its way in blockchain technologies. More broadly, the paper is
instrumental in forming a bridge between the research communities on security and on dependable systems and
networks. As Jean-Claude Laprie used to remind us, security is indeed one of the five fundamental attributes of
dependability. For these reasons, the selection committee has unanimously selected this ground-breaking publication
which is well-deserving of this award.”

About the Jean-Claude Laprie Award in Dependable Computing

The award was created in 2011, in honor of Jean-Claude Laprie (1944-2010), whose pioneering contributions to the concepts and methodologies of dependability were influential in defining and unifying the field of dependable and secure computing. The award recognizes outstanding papers that have significantly influenced the theory and/or practice of Dependable Computing.
