Simplified Explanation

The abstract describes a method for disabling Server Name Indication (SNI) encryption in a telecommunication network. The method involves a Domain Name System (DNS) server receiving a DNS query from a User Equipment (UE) containing a domain name to be converted to an IP address. The DNS server determines that SNI encryption should be deactivated for future traffic related to the domain name. The DNS query is then forwarded to an external DNS server, including a request to disable SNI encryption. The DNS server receives a DNS answer from the external DNS server, which includes the converted IP address and is free from encryption keys for SNI encryption. Finally, the DNS server forwards the DNS answer to the UE, ensuring that the UE is unable to encrypt SNI in subsequent traffic.


Original Abstract Submitted

A method for deactivating Server Name Indication, SNI, encryption in a telecommunication network, wherein said telecommunication network comprises a Domain Name System, DNS, server, said method comprising the steps of receiving, by said DNS server, from a User Equipment, UE, a DNS query comprising a Domain Name to be converted to an Internet Protocol, IP, address, determining, by said DNS server, that SNI encryption is to be deactivated for subsequent traffic associated with said Domain Name, forwarding, by said DNS server, said DNS query to an external DNS server, wherein said DNS query comprises said Domain Name and a request for deactivating SNI encryption, receiving, by said DNS server, from said external DNS server, a DNS answer, wherein said DNS answer comprises said converted IP address and wherein said DNS answer is free from encryption keys for encrypting SNI and forwarding, by said DNS server, said DNS answer comprising said converted IP address to said UE, wherein said DNS answer is free from encryption keys such that said UE is not able to encrypt said SNI in said subsequent traffic.
