6th International Workshop on LIGHTWEIGHT CRYPTOGRAPHY FOR SECURITY &PRIVACY (LightSEC 2025), September 01-03, 2025, Istanbul, Türkiye

LightSEC 2025 promotes and initiates novel research on security, privacy, and trust issues related to applications that fall under the umbrella of lightweight security. The term “lightweight” refers not only to conventional constraints on metrics such as computational and communication complexity, execution time (both throughput andlatency), power, energy, area, memory capacity, and bandwidth, but also to constraints concerning the sizes of ciphertexts, public and private keys, and the compactness of proofs in zero-knowledge protocols. As new applications based on novel and advanced cryptographic schemes become increasingly ubiquitous and provide immense value to society across sectors such as AI, blockchain, IoT, and 5G/6G, they also impact a larger portion of the public, raising numerous security and privacy concerns that must be thoroughly addressed before widespread deployment.

LightSEC 2025 enthusiastically welcomes papers on algorithms, protocols, techniques,and their secure and efficient implementations for applications utilizing advanced cryptographic algorithms such as homomorphic encryption, zero-knowledge proofs, secure multi-party computation, cryptographic consensus protocols in blockchain applications, threshold cryptography, and post-quantum cryptography.

Submission Instructions

The submissions must be anonymous with no author names, affiliations or obvious references. Submissions must not substantially duplicate work that any of the authors has published in a journal or a conference/workshop with proceedings or has submitted/is planning to submit before the author notification deadline to a journal or other conferences/workshops that have proceedings. Accepted submissions may not appear in any other conference or workshop that has proceedings.

The proceedings will be published in Springer-Verlag’s LNCS series. Hence, the final version of accepted papers will have to follow the LNCS guidelines (https://www.springer.com/gp/computer-science/lncs) using Springer’s standard fonts, font sizes, and margins with a total page limit of 20 pages including references and appendices. Submissions to LightSEC 2025 must follow the same format. Clearly marked supplementary materials may be appended without a page limit, but reviewers are neither required to read them nor will they be printed in the proceedings. Hence papers must be intelligible and self-contained within the 20-page bound.
