Converting pairing-based cryptosystems from composite to prime order setting – A comparative analysis

Journal of Mathematical Cryptology, 2018
Composite order pairing setting has been used to achieve cryptographic functionalities beyond what is attainable in prime order groups. However, such pairings are known to be significantly slower than their prime order counterparts.

Analysis of collision probability in Merkle trees in the random oracle model

Journal of Mathematical Cryptology
This work analyzes the probability of collisions in Merkle graphs, with a focus on a specific class of attacks in balanced Merkle trees. To provide a tractable model, each hash function is modeled as an independent random oracle with finite input space ...

Cross-primitive comparison in CP-ABE

Journal of Mathematical Cryptology
Ciphertext-Policy Attribute-Based Encryption (CP-ABE) is a cornerstone technique for fine-grained access control in encrypted data sharing, with pairing-based schemes having established the de facto standard.

On the security of the Courtois-Finiasz-Sendrier signature

Open Mathematics, 2018
We prove that a variant of the Courtois-Finiasz-Sendrier signature is strongly existentially unforgeable under chosen message attack in the random oracle model, assuming hardness of the Permuted Goppa Syndrome Decoding Problem (also known as the ...
