A Forward-Secure Public-Key Encryption Scheme* [PDF]
SSRN Electronic Journal, 2003 Cryptographic computations are often carried out on insecure devices for which the threat of key exposure represents a serious concern. Forward security allows one to mitigate the damage caused by exposure of secret keys. In a forward-secure scheme, secret keys are updated at regular periods of time; exposure of the secret key corresponding to a given ...

A Forward-Secure Digital Signature Based on Elliptic Curve
Dianxin kexue, 2015 The forward-secure digital signature is an important digital signature scheme.It requires that even if the attackers have already been given a signature key by invading a system in t time，it still can’t forge signatures before time t.In other words，the ...

Toward Forward Secure SSE Supporting Conjunctive Keyword Search
IEEE Access, 2019 The primitive of Searchable Symmetric Encryption (SSE) allows a server to perform search directly over encrypted documents. Recently, forward secure SSE (FSSE) has attracted significant attention due to its secure property for document update.

UC and EUC Weak Bit-Commitments Using Seal-Once Tamper-Evidence [PDF]
Scientific Annals of Computer Science, 2013 Based on tamper-evident devices, i.e., a type of distinguishable, sealed envelopes, we put forward weak bit-commitment protocols which are UC-secure. These commitments are weak in that it is legitimate that a party could cheat.

Identity-based puncturable signature scheme
Tongxin xuebao, 2021 To overcome the shortcomings of available forward-secure identity-based signature （IBS） scheme in terms of actual practicability and secret key update efficiency， the notion of identity-based puncturable signature （IBPS） scheme was proposed based on the ...

Forward-secure ciphertext-policy attribute-based encryption scheme
Tongxin xuebao, 2014 To mitigate the damage of key exposure in the context of ciphertext-policy attribute-based encryption (CP-ABE). The syntax and security model of forward-secure CP-ABE was presented. Then, a concreted forward-secure CP-ABE scheme was constructed.

A Modern View on Forward Security [PDF]
The Computer Journal, 2020 Abstract Forward security ensures that compromise of entities today does not impact the security of cryptographic primitives employed in the past. Such a form of security is regarded as increasingly important in the modern world due to the existence of adversaries with mass storage capabilities and powerful infiltration abilities ...

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 ...
