A Lightweight Policy Preserving EHR Sharing Scheme in the Cloud
IEEE Access, 2018 Electronic Health Record (EHR) is a digital health documentary. It contains not only the health-related records but also the personal sensitive information. Therefore, how to reliably share EHR through the cloud is a challenging issue.

Advanced Science, Volume 13, Issue 19, 2 April 2026.Elevated exogenous palmitic acid promotes the S‐palmitoylation of SRPK1 in endothelial cells, a dynamic process governed by ZDHHC24 and APT1. This post‐translational modification strengthens the interaction between SRPK1 and the E3 ubiquitin ligase MIB1, thereby facilitating the proteasomal degradation of SRPK1.

Comparing Lattices and Bilinear Parings in CP-ABE
De Cifris KoineCiphertext-Policy Attribute-Based Encryption enables fine-grained access control by binding ciphertext decryption to user attributes. While most practical schemes are pairing-based and rely on assumptions vulnera- ble to quantum attacks, lattice-based approaches offer post-quantum secu- rity at the cost of reduced expressiveness.

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.
