Error-Free Perfect Secrecy Systems
Shannon's fundamental bound for perfect secrecy says that the entropy of the secret message cannot be larger than the entropy of the secret key initially shared by the sender and the legitimate receiver. Massey gave an information theoretic proof of this result, however this proof does not require independence of the key and ciphertext.

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.

XOR Chain and Perfect Secrecy at the Dawn of the Quantum Era
In this article, we present a new method that achieves Shannon’s perfect secrecy. To achieve this property, we will introduce the triple XOR cancellation rule. The approach has two execution modes: digital signature and data encryption.

Perfect secrecy via compressed sensing [PDF]
In this paper we consider the compressive sensing based encryption and proposed the conditions in which the perfect secrecy is achievable. We prove that when the measurement matrix holds the Restricted Isometry Property (RIP) and the number of measurements is more than two times of the sparsity level, i.e., M ≥ 2k, the Shannon perfect secrecy condition

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.

Perfect Secrecy System Based on Chaotic Key Generator
Shannon defines perfect secrecy for a cryptographic system as such a cryptographic system in which the ciphertext yields no possible information about the plaintext.
