: Walking the Privacy Trailserver. In order to provide user-dependent services, service providers may ask the server to compute functions on the users’ data. We propose a new solution to this problem that guarantees data privacy (. an honest-but-curious server cannot access plaintexts), as well as that service providers can c

DNS-DNS: DNS-Based De-NAT Schemeoriginal IP address, which is often viewed as a privacy feature, making it harder to identify the communication of individuals devices behind the NAT. . is the reverse process: re-identifying communication flowing into and out of the NAT. De-NAT can be used for traffic management, security, and lawf

CLEF: Limiting the Damage Caused by Large Flows in the Internet Coreow detection has been previously explored, but the proposed approaches can be used on high-capacity core routers only at the cost of significantly reduced accuracy, due to their otherwise too high memory and processing overhead. We propose CLEF, a new large-flow detection scheme with low memory requ

Towards Video Compression in the Encrypted Domain: A Case-Study on the H264 and HEVC Macroblock Procs, so-called macroblocks, and is mainly divided into four operations: color conversion, Discrete Cosine Transform (DCT), quantization and entropic encoding. This operation is carried out easily on non-encrypted image. In this paper, we consider the case where such an execution is done in the encrypt

The Relation Between CENC and NEMO up to the birthday bound. In this work we consider two approaches in literature to improve it to beyond birthday bound security: CENC by Iwata (FSE 2006) and its generalization NEMO by Lefranc et al. (SAC 2007). Whereas recent discoveries on CENC argued optimal security, the state of the art of NEM

Enhanced Security of Attribute-Based Signatures security of ABS by presenting a strengthened simulation-based privacy definition and the first attribute-based signature functionality in the framework of universal composability (UC). Additionally, we show that the UC definition is equivalent to our strengthened experiment-based security definitio
