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.

A secure anonymous proxy signcryption scheme

Journal of Mathematical Cryptology, 2017
We introduce a new cryptographic primitive identity-based anonymous proxy signcryption which provides anonymity to the proxy sender while also providing a mechanism to the original sender to expose the identity of the proxy sender in case of misuse.

mRLWE-CP-ABE: A revocable CP-ABE for post-quantum cryptography

Journal of Mathematical Cryptology
We address the problem of user fast revocation in the lattice-based Ciphertext Policy Attribute-Based Encryption (CP-ABE) by extending the scheme originally introduced by Zhang and Zhang [Zhang J, Zhang Z.

Rigorous upper bounds on data complexities of block cipher cryptanalysis

Journal of Mathematical Cryptology, 2017
Statistical analysis of symmetric key attacks aims to obtain an expression for the data complexity which is the number of plaintext-ciphertext pairs needed to achieve the parameters of the attack. Existing statistical analyses invariably use some kind of

Differential experiments using parallel alternative operations

Journal of Mathematical Cryptology
The use of alternative operations in differential cryptanalysis, or alternative notions of differentials, is lately receiving increasing attention. Recently, Civino et al.

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.

Formalization of the Advanced Encryption Standard. Part I

, 2013
Summary. In this article, we formalize the Advanced Encryption Standard (AES). AES, which is the most widely used symmetric cryptosystem in the world, is a block cipher that was selected by the National Institute of Standards and Technology (NIST) as an ...
