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 infrastructure

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
Springer LNCS series (see
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

- 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 presentation.


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.
