Securing Update Propagation with Homomorphic Hashing
Homomorphic Hashing Folly open-source library
2019/3/4
In database replication, ensuring consistency when propagating updates is a challenging and extensively studied problem. However, the problem of securing update propagation against malicious adversari...
We develop a new methodology to assess cryptographic key strength using cloud computing, by calculating the true economic cost of (symmetric- or private-) key retrieval for the most common cryptograph...
Bidirectional Asynchronous Ratcheted Key Agreement without Key-Update Primitives
secure communication post-compromise security ratchet
2018/11/9
Following up mass surveillance and privacy issues, modern secure communication protocols now seek for more security such as forward secrecy and post-compromise security. They cannot rely on any assump...
AUTOMATED BUILDING DETECTION IN DENSE POINT CLOUD AND UPDATE OF OPEN SOURCE DATA BASES
Dense matching, Building detection Classification Digital Terrain Model openstreetmap point cloud
2018/11/9
In this paper a method of detecting buildings in dense populated city areas using a three-dimensional model, produced by aerial images, is described. Further to the detection of the outline of the bui...
Message-locked Encryption with File Update
Message-locked encryption symmetric key cryptography hash mode of operation
2018/5/11
Message-locked encryption (MLE) (formalized by Bellare, Keelveedhi and Ristenpart, 2013) is an important cryptographic primitive that supports deduplication in the cloud. Updatable block-level message...
