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 and latency), 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 these applications become increasingly ubiquitous and provide immense value to society, they also affect 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.
