Analysis of iCloud Private Relay Security
iCloud Private Relay is a service provided by Apple that protects the privacy of a user by encrypting DNS messages and sending these over multiple relays in order to hide the user's IP address. It is part of the iCloud+ subscription and thus requires a user to pay for additional security and privacy. The service is based on Oblivious DNS over HTTPS (ODoH) which was recently published as an experimental standard (RFC 9230). Possible goals of this Master's thesis are e.g.
- To analyse the security of the ODoH protocol
- To evaluate the privacy gain of this method
