GO-CP-ABE:group-oriented ciphertext-policy attribute-based encryption [PDF]
We introduce a variant of ciphertext-policy attribute-based encryption called group-oriented ciphertext-policy attribute-based encryption (GO-CP-ABE).

Ciphertext-Policy Attribute-Based Broadcast Encryption with Small Keys [PDF]
Broadcasting is a very efficient way to securely transmit information to a large set of geographically scattered receivers, and in practice, it is often the case that these receivers can be grouped in sets sharing common characteristics (or attributes). We describe in this paper an efficient ciphertext-policy attribute-based broadcast encryption scheme

In this comment paper, we point out a security flaw in a data access control system which is built on ciphertext-policy attribute-based encryption (CP-ABE) and attribute-based signature schemes.

Enhancing E‐Commerce Security Based on Involution Function Using Twin Key AES Cipher
In the realm of surging e‐commerce data and increasing digital transactions, ensuring end‐to‐end security is paramount to protect sensitive information and maintain user trust. The Advanced Encryption Standard (AES), a cornerstone of network security, relies on symmetric key encryption for secure communication.

Forward-secure ciphertext-policy attribute-based encryption scheme
To mitigate the damage of key exposure in the context of ciphertext-policy attribute-based encryption (CP-ABE). The syntax and security model of forward-secure CP-ABE was presented. Then, a concreted forward-secure CP-ABE scheme was constructed.

A Keyword-Searchable ABE Scheme From Lattice in Cloud Storage Environment
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.

A Private‐Identifier System From Scalable Private Set Union
Modern data‐driven collaborations, such as spanning healthcare analysis and advertising attribution, need to merge large identifier sets without revealing which records overlap. A private set union (PSU) protocol enables two parties, each holding a private set X and Y, to securely compute their union X ∪ Y without revealing any additional information ...

Ciphertext Policy Attribute Based Encryption with Intel SGX
Modern computing environments demand robust security measures to protect sensitive data and resources. Ciphertext-Policy Attribute-Based Encryption (CP-ABE) is a well-established encryption technique known for its fine-grained access control capabilities.

Security of discrete log cryptosystems in the random oracle and the generic model [PDF]
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
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 ...
