CP‐ABE with outsourced decryption and directionally hidden policy

Security and Communication Networks, 2016
AbstractCiphertext‐policy attribute‐based encryption (CP‐ABE) is a novel cryptographic primitive for access controlling. However, the existing CP‐ABE schemes are very inefficient as the decryptions involve many expensive pairing operations. Another drawback is that the access policy itself may disclose some privacies of the users.

Landscapes of HLA Mismatching in Contemporary Unrelated Haematopoietic Cell Transplantation

HLA, Volume 107, Issue 3, March 2026.
ABSTRACT Haematopoietic cell transplantation (HCT) with HLA‐mismatched unrelated donors (MMUD) offers access to curative therapy for patients lacking well‐matched donors. Accumulating evidence suggests that functional matching among allele‐mismatched pairs can significantly influence patient outcomes.
