The abstract, if you rearrange it and remove some of the jargon, is actually pretty comprehensible (to me, at least). > Searchable Symmetric Encryption aims at making possible searching over an encrypted database stored on an untrusted server while keeping privacy of both the queries and the data… This work proposes [a new, more efficient technique], which does not leak [whether or not] a newly inserted element matches previous search queries. Further TL;DR: a way to put an encrypted dataset on an untrusted server such that it can be efficiently searched without the server knowing the decryption key or even the search query. Queries cannot be rerun after more data is added (which would otherwise leak information about the encrypted dataset and/or encrypted query).
