pseudonyms unlinkability data exchange
2017/2/20
When data maintained in a decentralized fashion needs to be synchronized or exchanged between different databases, related data sets usually get associated with a unique identifier. While this approac...
We present an identity-based encryption (IBE) scheme in composite-order bilinear groups with
essentially optimal parameters: the ciphertext overhead and the secret key are one group element each and
...
With increased use of passive RFID tags, the need for secure lightweight identification protocols
arose. HB+ is one such protocol, which was proven secure in the detection-based model, but shown
bre...
