Data Querying with Ciphertext Policy Attribute Based Encryption

open access: yes, 2022
Data encryption limits the power and efficiency of queries. Direct processing of encrypted data should ideally be possible to avoid the need for data decryption, processing, and re-encryption. It is vital to keep the data searchable and sortable. That is, some information is intentionally leaked.

(Not Surprising) Attacks on Recent Pairing‐Free Attribute‐Based Encryption Schemes

open access: yesIET Information Security, Volume 2026, Issue 1, 2026.
The fact that designing secure and efficient identity or attribute‐based encryption (ABE) schemes requires the use of specific algebraic tools like bilinear pairings or lattices is well known in the cryptographic community. However, some journals whose main topics are not cryptographic still publish papers proposing, for instance, ABE schemes in ...

A Private Blockchain and IPFS‐Based Secure and Decentralized Framework for People Surveillance via Deep Learning Techniques

open access: yesIET Software, Volume 2026, Issue 1, 2026.
The modern metropolis essentially demands the use of state‐of‐the‐art, real‐time surveillance systems, which should be reliable, scalable, and respectful of privacy at the same time. Critical shortcomings in traditional architectures are single points of failure, poor scalability, frequent data breaches, and inadequately managed privacy.

Assessment of Practical Satellite Quantum Key Distribution Architectures for Current and Near‐Future Missions

open access: yesInternational Journal of Satellite Communications and Networking, Volume 43, Issue 3, Page 164-192, May/June 2025.
ABSTRACT Quantum key distribution (QKD) allows the generation of cryptographic keys beyond the computational hardness paradigm and is befitting for secure data transmission requiring long‐term security. The communication distance of fiber‐based QKD, however, is limited to a few hundred kilometers due to the exponential scaling of signal attenuation ...
