This book constitutes the proceedings of 25th International Symposium, SSS 2023, in Jersey City, NJ, USA, in October 2023. The 32 full papers presented together with 8 short papers were carefully reviewed and selected from 78 submissions. The conference was organized into five tracks reflecting major trends related to the conference: (i) Track A. Self-stabilizing Systems: Theory and Practice, (ii) Track B. Distributed and Concurrent Computing: Foundations, Fault-Tolerance and Scalability, (iii) Track C. Cryptogrophy and Security, (iv) Track D. Dynamic, Mobile and Nature-Inspired Computing Mobile Agents, (v) and Distributed Databases.

This book constitutes the refereed proceedings of the 23rd International Symposium on Stabilization, Safety, and Security of Distributed Systems, SSS 2021, held virtually, in November 2021. The 16 full papers, 10 short and 14 invited papers presented were carefully reviewed and selected from 56 submissions. The papers deal with 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.

This book constitutes the refereed proceedings of the 22nd International Symposium on Stabilization, Safety, and Security of Distributed Systems, SSS 2020, held in Austin, TX, USA, in November 2020. The 16 full papers, 7 short and 2 invited papers presented were carefully reviewed and selected from 44 submissions. The papers deal with 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.

This book constitutes the refereed proceedings of the 19th International Symposium on Stabilization, Safety, and Security of Distributed Systems, SSS 2017, held in Boston, MA, USA, in November 2017. The 29 revised full papers presented together with 8 revised short papers were carefully reviewed and selected from 68 initial submissions. This year the Symposium was organized into three tracks reflecting major trends related to self-* systems: Stabilizing Systems: Theory and Practice: Distributed Computing and Communication Networks; and Computer Security and Information Privacy.

This book constitutes the refereed proceedings of the 20th International Symposium on Stabilization, Safety, and Security of Distributed Systems, SSS 2018, held in Tokyo, Japan, in November 2018. The 24 revised full papers presented were carefully reviewed and selected from 55 submissions. The papers are organized into three tracks reflecting major trends related to distributed systems: theoretical and practical aspects of stabilizing systems; distributed networks and concurrency; and safety in malicious environments.

This book constitutes the refereed proceedings of the 18th International Symposium on Stabilization, Safety, and Security of Distributed Systems, SSS 2016, held in Lyon, France, in November 2016. This year the Program Committee was organized into three groups reflecting the major trends related to self-* systems: (a) Self-* and Autonomic Computing, (b)Foundations, and (c) Networks, Multi-Agent Systems, and Mobility.
