Revocable and Traceable Data Sharing and Encryption Methods in Cloud Computing Environments
Engineering Reports, Volume 8, Issue 7, July 2026.This paper proposes a revocable, traceable cloud data sharing scheme. It enhances multi‐authority attribute‐based encryption for fine‐grained access with immediate user revocation and precise leak tracking. Evaluations on a manufacturing platform show efficient performance, handling 1 GB files with re‐encryption under 4.3 s and strong privacy ...

How do gestural interactions support visuospatial cognition in STEM learning?
British Journal of Educational Technology, Volume 57, Issue 4, Page 1140-1162, July 2026.Abstract Existing literature shows that touchscreen devices can support learning of visuospatially rich STEM content. However, the mechanisms by which touchscreen devices support cognition in learning remains unclear. This study examined how gestural interactions afforded by touchscreen devices support visuospatial cognition in STEM learning by ...

Security of signed ELGamal encryption [PDF]
, 2005 Assuming a cryptographically strong cyclic group G of prime order q and a random hash function H, we show that ElGamal encryption with an added Schnorr signature is secure against the adaptive chosen ciphertext attack, in which an attacker can freely use

Directly revocable ciphertext-policy attribute-based encryption from lattices [PDF]
, 2020 Attribute-based encryption (ABE) is a promising type of cryptosystem achieving fine-grained access control on encrypted data. Revocable attribute-based encryption (RABE) is an extension of ABE that provides revocation mechanisms when user\u27s ...

Ciphertext-policy attribute based encryption supporting access policy update
, 2016 Attribute-based encryption (ABE) allows one-to-many encryption with static access control. In many occasions, the access control policy must be updated and the original encryptor might be required to re-encrypt the message, which is impractical, since ...
