Security of discrete log cryptosystems in the random oracle and the generic model [PDF]
, 1999 We introduce novel security proofs that use combinatorial counting arguments rather than reductions to the discrete logarithm or to the Diffie-Hellman problem. Our security results are sharp and clean with no polynomial reduction times involved.

(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 ...

Ciphertext-Policy Attribute Based Encryption with Selectively-Hidden Access Policy [PDF]
, 2021 In conventional Ciphertext-Policy Attribute-Based Encryption (CP-ABE), the access policy appears in plaintext form that might reveal confidential user information and violate user privacy.

A Keyword-Searchable ABE Scheme From Lattice in Cloud Storage Environment
IEEE Access, 2019 Currently, the security situation of data security and user privacy protection is increasingly serious in cloud environment. Ciphertext data storage can prevent the risk of user's privacy disclosure.

Securing Machine‐Type Communications: A Survey on Privacy Threats and Countermeasures
IET Information Security, Volume 2026, Issue 1, 2026.Machine‐type communication (MTC) is a fundamental enabler of the Internet of Things (IoT) and emerging 5G/6G networks, supporting massive deployments of heterogeneous and resource‐constrained devices. However, large‐scale data collection, persistent connectivity, and limited device capabilities introduce critical privacy challenges that are not ...

LIMA: Local and Lightweight Mutual Authentication for VANETs
IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.This work presents LIMA, a lightweight local authentication protocol for VANETs. It is a SAE J2735 compliant certificateless vehicle authentication that eliminates traditional PKI dependencies while providing geographic zone‐based security and time‐based attribute control.

IET Quantum Communication, Volume 7, Issue 1, January/December 2026.This paper was not transferred from another journal. ABSTRACT Software‐defined networking (SDN) consolidates network control at a centralised controller, making the southbound TLS‐protected channel between the controller and OpenFlow switches the principal security boundary of the entire network.

Verifiable Outsourced Decryption OO-CP-ABE Access Control Scheme with Hidden Policy [PDF]
Jisuanji gongcheng, 2019 In Ciphertext-Policy Attribute-Based Encryption(CP-ABE),the time required for data encryption and decryption is related to the complexity of the access structure,so implementing CP-ABE in mobile devices makes the device under greater computational ...
