Title
One Key To Sign Them All Considered Vulnerable: Evaluation Of Dnssec In The Internet
Abstract
We perform the first Internet study of the cryptographic security of DNSSEC-signed domains. To that end, we collected 2.1M DNSSEC keys for popular signed domains out of these 1.9M are RSA keys. We analyse the RSA keys and show that a large fraction of signed domains are using vulnerable keys: 35% are signed with RSA keys that share their moduli with some other domain and 66% use keys that are too short (1024 bit or less) or keys which modulus has a GCD > 1 with the modulus of some other domain. As we show, to a large extent the vulnerabilities are due to poor key generation practices, but also due to potential faulty hardware or software bugs.The DNSSEC keys collection and analysis is performed on a daily basis with the DNSSEC Keys Validation Engine which we developed. The statistics as well as the DNSSEC Keys Validation Engine are made available online, as a service for Internet users.
