The aim of the SCI workshop is to provide an international forum of scientific research and development to explore the security issues in the implementation and deployment of cryptographic solutions. We are interested in these main aspects: (1) vulnerabilities and defenses in the implementation of cryptographic algorithms; (2) vulnerabilities and defenses in the implementation of cryptographic protocols; (3) defective cryptographic algorithms and protocols deployed in the wild; (4) weak cryptographic keys and random numbers in the cryptographic implementation; (5) runtime cryptographic key attacks and protections; (6) certificates and key management; (7) misuse or abuse of cryptographic services; and (8) other topics on secure cryptographic implementations.

We try to promote secure cryptographic solutions in the Internet, by exploring and discussing the (in)security issues. We solicit submissions of original research papers on a wide range of topics, including but not limited to:

• Secure implementations of crypto algorithms & protocols
• Fuzzing and vulnerabilities of crypto algorithms & protocols
• Measurement of cryptographic solutions in the wild, defective or updated
• Designs of random bit generators
• Weak cryptographic keys and defective random bit generators
• Side channel attacks and defenses
• Cryptographic key protections and memory attacks
• PKI certificate services and key management
• HTTPS/TLS vulnerabilities and attacks
• Measurement and bugs of certificate-based solutions
• Audit and monitoring of cryptographic services
• Physical attacks and defenses of cryptographic implementation
• Verification and evaluation of cryptographic implementation
• High-performance cryptographic engines
• Cryptographic hardware
• Cryptography for Blockchain
• Cryptography for IoT/CPS
• Cryptography for the Cloud
• Cryptography for Mobile systems
• Cryptography for VANET

We are especially interested in papers with novel ideas, position papers, pilot studies, and initial findings. ACNS will also award a best papers from the 2025 ACNS workshops (ADSC, AIBlock, AIHWS, AIoTS, CIMSS, Cloud S&P, SCI, SecMT, SiMLA and S&P-FL), with 500 EUR prize sponsored by Springer. Meanwhile, the workshop will include an interesting keynote talk, which will be announced on the workshop web site as arrangements are finalized.

Prospective authors are invited to submit manuscripts describing original work. The manuscript has to be written in English and in PDF format. All submissions must follow the original LNCS format (accessible on the Springer LCNS author guidelines webpage) with a page limit of 20 pages including all references and appendices.

The proceedings of the SCI workshop will be published by Springer in the LNCS series.
