From March 2017 to February 2018, PRISMACLOUD contributed to ETSI TC CYBER STF529 (Specialist Task Force 529) with title “Attribute Based Encryption – Common protocol for data access control for Cloud, Mobile and IoT.” The outcome of the STF was the Technical Specification (TS) 103 532.

The work on PRISMACLOUD’s SECOSTOR tool directly influenced the STF529 work. In deliverable D4.3 - "Efficient Sharing-Based Storage Protocols for Mixed Adversaries", cryptographic access-control mechanisms are discussed where ABE is considered as a possible technique to encrypt", shares of sensitive data at the cloud provider which motivates the use of ABE for enhanced access control mechanisms to reduce the trust in cloud storage providers.
