The paper 'SBAC: Substitution cipher access control based on blockchain for protecting personal data in metaverse', written by Seo Jung-won of the Blockchain & Software Laboratory (first author, doctoral, supervisor Park Soo-yong) and Professor Park Soo-yong (corresponding author), has been accepted for publication in Future Generation Computer Systems.

Future Generation Computer Systems is ranked 10/111 in JCR, placing it in the top 10% of journals in theory and methods in computer science.

The paper proposes a new encryption technique using substitution ciphers and blockchain technology to improve the speed of data encryption and decryption in metaverse environments, where real-time behaviour matters. The proposal uses blockchain to resolve the centralization problem of existing symmetric-key encryption, and presents a way of effectively overcoming the speed problem of asymmetric-key encryption.
