# CoSMeDis: A confidentiality-verified distributed social media platform

 Title: CoSMeDis: A confidentiality-verified distributed social media platform Authors: Thomas Bauereiss (thomas /at/ bauereiss /dot/ name) and Andrei Popescu Submission date: 2021-08-16 Abstract: This entry contains the confidentiality verification of the (functional kernel of) the CoSMeDis distributed social media platform presented in [1]. CoSMeDis is a multi-node extension the CoSMed prototype social media platform [2, 3, 4]. The confidentiality properties are formalized as instances of BD Security [5, 6]. The lifting of confidentiality properties from single nodes to the entire CoSMeDis network is performed using compositionality and transport theorems for BD Security, which are described in [1] and formalized in a separate AFP entry.
