Dear all,

due to several requests, we extended the submission deadline of SSS to
August 19th (with an abstract deadline on August 16th).

Please find more details (including information about our keynote speakers)
below as well as our website

Please contact us in case you need any further information.

We are looking forward to your submissions!

special issue of Theoretical Computer Science.


SSS is an international forum for researchers and practitioners in the
design and development of distributed systems with a focus on systems that
are able to provide guarantees on their structure, performance, and/or
security in the face of an adverse operational environment. The symposium
encourages submissions of original contributions on fundamental research
and practical applications concerning topics in the four symposium tracks:

Track A. Self-stabilizing Systems: Theory and Practice

Self-stabilizing systems; Self-stabilizing protocols and algorithms;
Practically-stabilizing systems; Variants of Self-stabilization;
Topological Stabilization; Stabilization and self-* properties in hardware,
software, and middleware design; Self-stabilizing  software-defined

Track B.  Foundations of Concurrent and Distributed Computing

Distributed and concurrent algorithms and data structures; Shared and
transactional memory; Synchronization protocols; Distributed graph
algorithms; Graph-theoretic concepts for communication networks;
Peer-to-peer networks and dynamic networks; High-performance,  cluster,
cloud, and grid computing; Game theory and economical aspects of
distributed computing; Formal methods, validation, verification, and

Track C. Mobile and Robot Computing

Self-organization in mobile agents; mobile robots; mobile sensor networks;
mobile ad-hoc networks; population protocols; programmable matter;
nanoscale robots; biologically-inspired systems; and related new models.

Track D. Fault tolerance, Security, and Privacy

Network security; Privacy; Internet-of-things security; Cloud security;
Mobile sensor networks/ad-hoc networks security; Verifiable/fault-tolerant
computing; Anomaly and networked malware detection; Blockchain technologies
and cryptocurrencies; Byzantine-fault tolerance and distributed consensus
protocols; Secure multi-party computation; Applied cryptography.

Papers are to be submitted electronically through EasyChair:

All submissions must conform to the formatting instructions of the Springer
LNCS series
Each submission must be in English, in PDF format.

All submissions must be anonymous. We will use a somewhat relaxed
implementation of double-blind peer review this year: you are free to
disseminate your work through arXiv and other online repositories and give
presentations on your work as usual. However,  please make sure you do not
mention your own name or affiliation in the submission, and please do not
include obvious references in the text that reveal your identity. A
reviewer who has not previously seen the paper should be able to read it
without accidentally learning the identity of the authors. Please feel free
to ask the PC chairs if you have any questions about the double-blind
policy of SSS 2021.

There are two types of submission: regular paper and brief announcement.

- A regular submission must not exceed 15 pages (including the title,
authors, abstract, figures, and references). Additional necessary details
for an expert to verify the main claims of the submission may be included
in a clearly marked appendix if extra space is needed.

- A brief announcement submission must not exceed 5 pages and should not
include any appendix.

Any submission deviating from these guidelines will be rejected without
consideration of its merits. It is recommended that a regular submission
begins with a succinct statement of the problem being addressed, a summary
of the main results or conclusions,  a brief explanation of their
significance, a brief statement of the key ideas, and a comparison with
related work, all tailored to a non-specialist. Technical development of
the work, directed to the specialist, should follow. Papers outside of the
conference scope will be rejected without review. If requested by the
authors on the cover page, a regular submission that is not selected for a
regular presentation will also be considered for the brief announcement
format. This will not affect the consideration of the paper for a regular

Prizes will be given to the best regular paper and best student regular
paper. A regular paper is eligible for the best student paper if at least
one of its authors is a full-time student at submission time. Authors
should clearly indicate whether their submission is eligible to be
considered for the best student paper award (e.g., using a \thanks in the
title). The PC may decline to confer awards or may split awards.
