A New Functional Encryption for Multidimensional Range Query
Functional Encryption Multidimensional Range Query
2017/10/9
Functional encryption, which emerges in the community recently, is a generalized concept of traditional encryption (e.g. RSA and AES). In traditional encryption scheme, decrypting a ciphertext with a ...
Improved Reconstruction Attacks on Encrypted Data Using Range Query Leakage
Encrypted database leakage
2017/7/24
We analyse the security of database encryption schemes supporting range queries against persistent adversaries. Security against such an adversary captures, among other things, the privacy of the clie...
