It is proved that the proposed scheme satisfies correctness and perfect secrecy, thereby providing unconditional security against unauthorized coalitions while outperforming existing code-based secret sharing schemes in terms of supported secret size, scalability, and practical runtime.
This work introduces a new PSU protocol that is simple, efficient, and secure against known during-execution leakage and hashing-related leakage without relying on Cuckoo Hashing, and achieves linear complexity.

By utilizing any secure symmetric-key encryption scheme as a black-box primitive, this paper demonstrates a method for constructing a symmetric-key encryption scheme that remains secure even in the presence of partial key leakage.

Leveraging TFSS, ThORY achieves leakage-free keyword search and document identifier retrieval under a (t,p)-threshold model, hiding access, search, and volume patterns against any adversary corrupting fewer than t servers.

This work considers N secrets, of which N are linearly independent input values and the remaining N -K secrets are determined by linear computations on these inputs, and analyses the existence of LERS-derived leakage that exploits this structure.
In Incorrect-Plaintext Attacks (IPA), a malicious Data Owner (DO) compromises system security by encrypting incorrect plaintext, while a malicious Data User (DU) undermines system fairness by falsely claiming decryption failure even when the plaintext is valid. Both security and fairness vulnerabilities can be further...
