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

IET 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 ...

Revisiting the Security of the Lightweight Stream Cipher Draco: New Observation and TMDTO Attacks

IET Information Security, Volume 2026, Issue 1, 2026.
Draco is a lightweight small‐state stream cipher proposed in 2022. It is designed to provide a 128‐bit security level and be provably secure against time‐memory‐data trade‐off (TMDTO) attacks. In this paper, we revisit the security of Draco against TMDTO attacks.
