On Forward-Secure Storage [PDF]
, 2006 We study a problem of secure data storage in a recently introduced Limited Communication Model. We propose a new cryptographic primitive that we call a Forward-Secure Storage (FSS). This primitive is a special kind of an encryption scheme, which produces huge (5 GB, say) ciphertexts, even from small plaintexts, and has the following non-standard ...

A Secure Traitor Tracing Scheme against Key Exposure
, 2005 Copyright protection is a major issue in distributing digital content. On the other hand, improvements to usability are sought by content users. In this paper, we propose a secure {\it traitor tracing scheme against key exposure (TTaKE)} which contains ...

QuickSync: A Quickly Synchronizing PoS-Based Blockchain Protocol
, 2021 To implement a blockchain, we need a blockchain protocol for all the nodes to follow. To design a blockchain protocol, we need a block publisher selection mechanism and a chain selection rule.

Novel construction of forward-secure public-key encryption in the standard model
Tongxin xuebao, 2014 All existing provably secure forward-secure public-key encryption schemes in the literature were only proven to be chosen-plaintext secure. A novel forward-secure public-key encryption scheme without random oracles was pro-posed.

Forward-Secure Public-Key Encryption Scheme Based on SM9 [PDF]
Jisuanji kexue yu tansuoIn the traditional hybrid cryptosystem, an attacker can generate the previously used session key to decrypt session contents encrypted under the session key due to the leakage of the current private key.

Forward-Secure Edge Authentication for Graphs
The Computer Journal, 2021 AbstractThe edge authentication of graphs has been studied in the literature because graphs are one of the most widely used data organization structures. The majority of such schemes cannot be used to authenticate general directed graphs (GDGs); other schemes cannot be used for addressing either the issue of dynamic update or the issue of information ...

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Introduction Pre‐dilution online hemodiafiltration (Pre‐HDF) is predominantly used in Japan, whereas post‐dilution online HDF (Post‐HDF) is more common in Europe. An asymmetric cellulose triacetate (ATA) membrane may improve biocompatibility.

HybridPKE: A forward-secure non-interactive quantum-safe hybrid key exchange scheme
Engineering Science and Technology, an International Journal, 2022 The schemes submitted to NIST call for standardization of post-quantum cryptography have some common drawbacks in terms of decryption failure probability, scalability, and switching issues from pre-quantum to post- quantum cryptography. In this paper, we

Forward Secure Ring Signature without Random Oracles [PDF]
, 2011 In this paper, we propose a forward secure ring signature scheme without random oracles. With forward security, if a secret key of a corresponding ring member is exposed, all previously signed signatures containing this member remain valid. Yet the one who has stolen the secret key cannot produce any valid signature belonged to the past time period ...

A Practical Searchable Symmetric Encryption Scheme for Smart Grid Data
, 2018 Outsourcing data storage to the remote cloud can be an economical solution to enhance data management in the smart grid ecosystem. To protect the privacy of data, the utility company may choose to encrypt the data before uploading them to the cloud ...
