Unshared Secret Key Cryptography: Finite Constellation Inputs and Ideal Secrecy Outage
Shuiyin Liu, Yi Hong, Emanuele Viterbo
The Unshared Secret Key Cryptography (USK), recently proposed by the authors, guarantees Shannon's ideal secrecy and perfect secrecy for MIMO wiretap channels, without requiring se…
Guaranteeing Positive Secrecy Capacity with Finite-Rate Feedback using Artificial Noise
Shuiyin Liu, Yi Hong, Emanuele Viterbo
While the impact of finite-rate feedback on the capacity of fading channels has been extensively studied in the literature, not much attention has been paid to this problem under s…
Unshared Secret Key Cryptography
Shuiyin Liu, Yi Hong, Emanuele Viterbo
Current security techniques can be implemented with either secret key exchange or physical layer wiretap codes. In this work, we investigate an alternative solution for MIMO wireta…
Artificial Noise Revisited
Shuiyin Liu, Yi Hong, Emanuele Viterbo
The artificial noise (AN) scheme, proposed by Goel and Negi, is being considered as one of the key enabling technology for secure communications over multiple-input multiple-output…
