| Abstract | The certificate authority (CA) PKI system has been used for decades as a means of providing domain identity verification services throughout the Internet, but a growing body of evidence suggests that our trust in this system is misplaced. A recently proposed CA alternative, Convergence, extends the Network Perspectives system of multi-path probing to perform certificate verification. Unfortunately, adoption of Convergence and other SSL/TLS trust enhancements has been slow, in part because it is unknown how these systems perform against large workloads and realistic conditions. In this work we ask the question "What if all certificates were validated with Convergence?" We perform a case study of deploying Convergence under realistic workloads with a university-wide trace of real-world HTTPS activity. By synthesizing Convergence requests, we effectively force perspectives-based verification on an entire university in simulation. We demonstrate that through local and server caching, a single Convergence deployment can meet the requirements of millions of SSL flows while imposing under 0.1% network overhead and requiring as little as 108 ms to validate a certificate, making Convergence a worthwhile candidate for further deployment and adoption. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
