Robust Secure Authentication and Data Storage With Perfect Secrecy
Cryptography, 2018 We consider an authentication process that makes use of biometric data or the output of a physical unclonable function (PUF), respectively, from an information theoretical point of view.

From perfect secrecy to perfect safety & security: Cryptography-based analysis of endogenous security [PDF]
Security and Safety, 2023 In this paper, we propose a conjecture that endogenous security without any prior knowledge is similar to perfect secrecy without any prior knowledge.

ADDING PERFECT FORWARD SECRECY TO KERBEROS [PDF]
Journal of Engineering, 2010 Kerberos system is a powerful and widely implemented authentication system. Despite this fact it has several problems such as the vulnerability to dictionary attacks which is solved with the use of public key cryptography.

Symmetric Blind Decryption with Perfect Secrecy [PDF]
Journal of Computer Networks and Communications, 2017 A blind decryption scheme enables a user to query decryptions from a decryption server without revealing information about the plain-text message. Such schemes are useful, for example, for the implementation of privacy-preserving encrypted file storages ...

XOR Chain and Perfect Secrecy at the Dawn of the Quantum Era
Cryptography, 2023 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.

Refinements and Extensions of Ziv’s Model of Perfect Secrecy for Individual Sequences [PDF]
EntropyWe 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 ...

On the Beneficial Role of a Finite Number of Scatterers for Wireless Physical Layer Security
IEEE Access, 2020 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 ...

Novel Noise Injection Scheme to Guarantee Zero Secrecy Outage under Imperfect CSI
Entropy, 2023 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 ...
