Position based cryptography (PBC), proposed in the seminal work of Chandran, Goyal,
Moriarty, and Ostrovsky (SIAM J. Computing, 2014), aims at constructing cryptographic schemes
in which the identit...

2016/1/3
A serious concern with quantum key distribution (QKD)
schemes is that, when under attack, the quantum devices in a real-life
implementation may behave differently than modeled in the security
proof...
We consider what constitutes identities in cryptography. Typical examples include your name and
your social-security number, or your ¯ngerprint/iris-scan, or your address, or your (non-revoked) ...
