A Unified Framework for Trapdoor-Permutation-Based Sequential Aggregate Signatures
Aggregate signatures trapdoor permutations ideal cipher model
2018/1/19
We give a framework for trapdoor-permutation-based sequential aggregate signatures (SAS) that unifies and simplifies prior work and leads to new results. The framework is based on ideal ciphers over l...
Practical and Robust Secure Logging from Fault-Tolerant Sequential Aggregate Signatures
Sequential Aggregate Signatures Fault-Tolerance Secure Logging
2017/9/28
Keeping correct and informative log files is crucial for system maintenance, security and forensics. Cryptographic logging schemes offer integrity checks that protect a log file even in the case where...
A Generic Approach to Identity-based Sequential Aggregate Signatures: New constructions from 2-level HIBE Schemes
Identity-based Signatures Sequential Aggregate Signatures the CDH Assumption
2017/4/12
Identity-based sequential aggregate signature (IBSAS) schemes are usually applied to secure network routing and sensor networks, since they allow multiple signers to sequentially produce a short signa...
Sequential aggregate signature (SAS) is a special type of public-key signature that allows a signer to add his signature into a previous aggregate signature in sequential order. In this case, since ma...
Sequential Aggregate Signatures with Lazy Verification from Trapdoor Permutations
public-key cryptography / aggregate signatures RSA BGPsec
2012/3/28
Sequential aggregate signature schemes allow n signers, in order, to sign a message each, at a lower total cost than the cost of n individual signatures. We present a sequential aggregate signature sc...
History-Free Sequential Aggregate Signatures
public-key cryptography / Aggregation Signature History-Freeness
2012/3/28
Aggregation schemes allow to combine several cryptographic values like message authentication codes or signatures into a shorter value such that, despite compression, some notion of unforgeability is ...

Aggregation schemes allow to combine several cryptographic values like message authentication codes or signatures into a shorter value such that, despite compression, some notion of unforgeability is ...
Sequential Aggregate Signatures from Trapdoor Permutations
Sequential Aggregate Signatures Trapdoor Permutations
2009/4/9
An aggregate signature scheme (recently proposed by Boneh, Gentry, Lynn, and Shacham)
is a method for combining n signatures from n different signers on n different messages into
one signature of un...
Sequential Aggregate Signatures and Multisignatures without Random Oracles
sequential aggregate signatures multisignatures random oracles
2008/11/6
We present the first aggregate signature, the first multisignature,
and the first verifiably encrypted signature provably secure without
random oracles. Our constructions derive from a novel applic...
Ordered Multisignatures and Identity-Based Sequential Aggregate Signatures,with Applications to Secure Routing
Digital signatures identity-based signatures multisignatures
2008/5/22
We construct two new multiparty digital signature schemes that allow multiple signers to
sequentially produce a compact, fixed-length signature. First, we introduce a new primitive
that we call orde...
