I investigate current proposals for post-quantum TLS, but more importantly we propose a more efficient TLS handshake that makes use of trade-offs presented by post-quantum cryptographic primitives (which were not as profound in pre-quantum primitives). This more efficient protocol we call KEMTLS. Benchmarks in several different settings for all variants of post-quantum TLS show that KEMTLS is efficient, and we also have an extensive analysis of the security of KEMTLS./p>/div>/a>div classbtn-links>a classbtn btn-outline-primary btn-page-header btn-sm href/publication/thesis/thesis.pdf target_blank relnoopener>PDF/a>a href# classbtn btn-outline-primary btn-page-header btn-sm js-cite-modal data-filename/publication/thesis/cite.bib>Cite/a>a classbtn btn-outline-primary btn-page-header btn-sm href/project/kemtls/>Project/a>/div>/div>/div>/div>/div>/section>section idpublications classhome-section wg-collection>div classhome-section-bg>/div>div classcontainer>div classrow>div classsection-heading col-12 col-lg-4 mb-3 mb-lg-0 d-flex flex-column align-items-center align-items-lg-start>h1 classmb-0>Recent Publications/h1>/div>div classcol-12 col-lg-8>div classmedia stream-item view-compact>div classmedia-body>div classsection-subheading article-title mb-0 mt-0>a href/publication/pq-wireguard/>Revisiting PQ WireGuard: A Comprehensive Security Analysis With a New Design Using Reinforced KEMs/a>/div>a href/publication/pq-wireguard/ classsummary-link>div classarticle-style>WireGuard is a VPN protocol with an efficient, DH-based handshake.
