Fast Large Integer Modular Addition in GF(p) Using Novel Attribute-Based Representation
IEEE Access, 2019 Addition is an essential operation in all cryptographic algorithms. Higher levels of security require larger key sizes and this becomes a limiting factor in GF(p) using large integers because of the carry propagation problem.

Privacy-Preserving Cryptography: Attribute-Based Signatures and Updatable Credentials
, 2022 In this thesis we analyze two privacy-preserving attribute-based cryptographic primitives: attribute-based signatures (ABS) and updatable anonymous credentials (UAC). ABS schemes allow users to authenticate messages in a privacy-preserving manner while proving that their information encoded as attributes in their secret keys satisfy a policy.
