MIDDLEBOX-AWARE

Middleboxes are widely deployed in order to enhance security and performance in networking. As communication over TLS becomes increasingly common, however, the end-to-end channel model of TLS undermines the efficacy of middleboxes. Existing solutions, such as ‘SplitTLS', which intercepts TLS sessions, often introduce significant security risks by installing a custom root certificate or sharing a private key. Many studies have confirmed security vulnerabilities when combining TLS with middleboxes, which include certificate validation failures, use of obsolete ciphersuites, and unwanted content modification. To address the above issues, we introduce a middlebox-aware TLS protocol, dubbed maTLS, which allows middleboxes to participate in the TLS session in a visible and auditable fashion. Every participating middlebox now splits a session into two segments with their own security parameters in collaboration with the two endpoints. The maTLS protocol is designed to authenticate the..
