Refinements and Extensions of Ziv’s Model of Perfect Secrecy for Individual Sequences [PDF]
We refine and extend Ziv’s model and results regarding perfectly secure encryption of individual sequences. According to this model, the encrypter and the legitimate decrypter share a common secret key that is not shared with the unauthorized ...

Novel Noise Injection Scheme to Guarantee Zero Secrecy Outage under Imperfect CSI
The paper proposes a novel artificial noise (AN) injection strategy in multiple-input single-output multiple-antenna-eavesdropper (MISOME) systems under imperfect channel estimation at the legitimate channel to achieve zero secrecy outage probability ...

On the Beneficial Role of a Finite Number of Scatterers for Wireless Physical Layer Security
We show that for a legitimate communication under multipath quasi-static fading with a reduced number of scatterers, it is possible to achieve perfect secrecy even in the presence of a passive eavesdropper for which no channel state information (CSI) is ...

Perfect Omniscience, Perfect Secrecy, and Steiner Tree Packing [PDF]
We consider perfect secret key generation for a ``pairwise independent network'' model in which every pair of terminals share a random binary string, with the strings shared by distinct terminal pairs being mutually independent. The terminals are then allowed to communicate interactively over a public noiseless channel of unlimited capacity.

Counter Mode of the Shannon Block Cipher Based on MPF Defined over a Non-Commuting Group
In this paper, we present a counter mode of a Shannon block cipher based on the matrix power function. We make use of the matrix power function to define a single round symmetric cipher.

Artificial Noise Aided Secure Transmission for Active RIS-Aided NOMA Networks
A secrecy rate maximization problem for active reconfigurable intelligent surface (RIS) aided non-orthogonal multiple access networks has been studied in this paper. Assuming that the perfect channel state information is available, we aim to maximize the
