Towards an in-depth understanding of privacy parameters for randomized sanitization mechanisms
Anonymity Differential Privacy
2017/9/18
Differential privacy, and close other notions such as dχdχ-privacy, is at the heart of the privacy framework when considering the use of randomization to ensure data privacy. Such a guarantee is alway...
By definition, fully homomorphic encryption (FHE) schemes
support homomorphic decryption, and all known FHE constructions are
bootstrapped from a Somewhat Homomorphic Encryption (SHE) scheme

2015/12/24
We initiate the study of sanitizable signatures over encrypted data. While previous solutions for sanitizable signatures require the sanitizer to know, in clear, the original message-signature pair in...
