Seminar: Bojan Spasic “Searchable Symmetric Encryption” (Apr 18, 2018)

Apr 18, 2018 – 12.30 – room P.2NO8.08

Speaker: Bojan Spasic (ULB)

Title: “Searchable Symmetric Encryption”
Short abstract: “Searchable Symmetric Encryption (SSE) has received a lot of research attention recently. To date, SSE schemes seem to provide the best tradeoffs between efficiency and security among different encrypted search solutions (e.g. property-preserving encryption, fully-homomorphic encryption, ORAM, functional encryption). Informally, SSE schemes encrypt a search structure which is outsourced to an untrusted server (e.g. in the cloud) together with the corresponding encrypted data collection. SSE enables clients to privately query the search structure in order to retrieve matching documents from the data collection. SSE has been studied in different security models and tradeoffs between security, efficiency and query expressiveness have been explored.”

Seminar: François Gerard “BLISS: Bimodal Lattice Signature Scheme” (Mar 14, 2018)

Mar 14, 2018 – 12.30 – room P.2NO8.08

Speaker: François Gerard (ULB)

Title: “BLISS: Bimodal Lattice Signature Scheme”
Short abstract: “In 2009, Lyubashevsky proposed the first provably secure lattice-based signature using the Fiat-Shamir paradigm. It’s security depends on a rejection step during the signature procedure. For this rejection sampling technique to be efficient, one must use a large distribution for the nonce resulting in large signatures. A few years later, Ducas and al. proposed a new scheme called BLISS optimizing this crucial step of rejection to decrease the overall size of the signature.”
