In recent weeks multiple proposals for schemes allowing contact tracing for combating the spread of COVID-19 have been published (e.g., DP-3T, Google and Apple, and PACT). Many of those proposals try to implement this functionality in a decentralized and privacy-preserving manner using Bluetooth Low Energy (BLE). In this talk, we will describe Bluetooth based contact tracing and the difference between centralized and decentralized approaches. We will then present "Hashomer'', our proposal for a contact tracing scheme tailored for the Israeli Ministry of Health's ``Hamagen'' application, and describe its security and privacy properties. A prototype implementation of this design can be found at https://github.com/eyalr0/HashomerCryptoRef.
