Monero is a cryptocurrency that has rapidly gained popularity since its launch in April 2014. The source of its growth can be mainly attributed to its unique privacy properties that go well beyond the...
Efficient Distributed Tag-Based Encryption and its Application to Group Signatures with Efficient Distributed Traceability
Group signatures distributed traceability distributed public-key encryption
2016/1/6
In this work, we first formalize the notion of dynamic group signatures with distributed traceability,
where the capability to trace signatures is distributed among n managers without requiring any i...

Attribute-Based Encryption Ciphertext-Policy Key Abuse
2015/12/29
As a sophisticated mechanism for secure fine-grained access
control, ciphertext-policy attribute-based encryption (CP-ABE) is a
highly promising solution for commercial applications such as cloud co...

Radio Frequency Identification (RFID) applications have spread all over the world and, in order to provide their security and pri-vacy, researchers proposed different kind of protocols. In this pa-per...
Traceability codes are combinatorial objects introduced by Chor,
Fiat and Naor in 1994 to be used in traitor tracing schemes to protect
digital content. A k-traceability code is used in a scheme to ...
Democratic Group Signatures with Threshold Traceability
democratic group signature anonymity traceability
2009/6/3
Recently, democratic group signatures(DGSs) particularly
catch our attention due to their great °exibilities, i.e., no group manager,
anonymity, and individual traceability. In existing DGS schemes,...
