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 ...

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 ...

Forward-Secure Group Encryptions from Lattices
, 2021 Group encryption (GE) is a fundamental anonymity primitive analogue of group signature, which guarantees the decryption ability of recipients to specific ciphertexts while hiding these users within a crowd.

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.

Forward-secure edge authentication for graphs
, 2022 The 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 ...

Efficient Anonymous Authentication for Wireless Body Area Networks
IEEE Access, 2022 Advances in integrated circuit and wireless communication technologies are making wireless body area networks (WBANs) an increasingly important medical paradigm. By collecting, uploading, and processing real-time physical parameters, WBANs assist clients

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 ...

Forensic mental health services as a risk escalator: a case study of ideals and practice
, 2004 Medium/low secure units occupy a central role in forensic mental health care, bridging high secure and community services. Although outcomes, assessed in terms of readmission and identified reoffending, have been evaluated, little research exploring ...

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.
