Sequential Half-Aggregation of Lattice-Based Signatures

With Dilithium and Falcon, NIST selected two lattice-based signature schemes during their post-quantum standardization project. Whereas Dilithium follows the Fiat-Shamir with Aborts (Lyubashevsky, Asiacrypt’09) blueprint, Falcon can be seen as an optimized version of the GPV-paradigm (Gentry et al., STOC’06).

Alternative Formalization and Implementation of Sequential Aggregate Signatures

2009 Second International Workshop on Computer Science and Engineering, 2009
This paper studies the construction of sequential aggregate signatures from any existentially unforgeable digital signature scheme and investigates whether the security of a sequential aggregate signature in this signature-based framework can be reduced to that of the underlying signatures.

From Rerandomizability to Sequential Aggregation: Efficient Signature Schemes Based on SXDH Assumption

2020
An aggregate signature allows one to generate a short aggregate of signatures from different signers on different messages. A sequential aggregate signature (SeqAS) scheme allows the signers to aggregate their individual signatures in a sequential manner.

Practical and Robust Secure Logging from Fault-Tolerant Sequential Aggregate Signatures

2017
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 an attacker has broken into the system.

On-Line Signature Verification Using Symbolic Aggregate Approximation (SAX) and Sequential Mining Optimization (SMO)

2014 13th International Conference on Machine Learning and Applications, 2014
Signatures are the single most widely used method of identifying an individual but they carry with them an alarmingly significant number of vulnerabilities, implying the need for an effective and robust method of precisely identifying an individual's signature. The signature of an individual is visually acquired by using a pen-based tracking system [1],

A Unified Framework for Trapdoor-Permutation-Based Sequential Aggregate Signatures

2018
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 large domains, which have recently been shown to be realizable in the random oracle model.
