A Probability‐Aware AI Framework for Reliable Anti‐Jamming Communication
CAAI Transactions on Intelligence Technology, Volume 11, Issue 2, Page 349-366, April 2026.ABSTRACT Adversarial jamming attacks have increased on communication systems, causing distortion and threatening transmissions. Typical attacks rely on traditional, well‐defined cryptographic protocols and frequency‐hopping techniques. Nevertheless, these techniques become vulnerable when facing intelligent jammers.

Ciphertext-policy attribute-based encryption with key-delegation abuse resistance [PDF]
, 2016 Attribute-based encryption (ABE) is a promising cryptographic primitive that allows one-to-many encryption. In such a system, users' private keys are linked to their access rights.

IET Blockchain, Volume 6, Issue 1, January/December 2026.ABSTRACT Bidding transactions are widely used in scenarios such as government procurement and corporate tendering. However, while traditional blockchain achieves transparency in transactions, it also poses a risk of sensitive information such as bidder identity, quotation, and time being leaked, thereby undermining the fairness and compliance of ...
