ID-Based Cryptography and Attribute-Based Cryptography
2023Identity and attribute-based cryptosystems have now become the most interesting research area in cryptography. Id-based and attribute-based cryptography both are improved variants of public-key cryptography. The identity-based cryptography is based on the identity of the user, such as email address, IP address, or mobile number.

An improved attribute-based signature using elliptic curve cryptography
Journal of Discrete Mathematical Sciences & CryptographyThe attribute-based signature(ABS) scheme enables users to sign messages based on their attributes while keeping their identities private. ECC provides strong security with smaller key sizes, enhancing the efficiency & practicality of the system. To address the high overhead of traditional ABS schemes, an improved attribute based signature scheme ...

AB-OR: Improving the Efficiency in Onion Routing Using Attribute Based Cryptography
2013Onion routing has been employed as a technique for ensuring anonymous communication over a public channel to ensure the integrity of the message as well as the privacy of the contending entities amidst untrusted routers. The technique ensures that the actual data as well as the meta-data in the packet are hidden from the prying intermediaries.

ATTRIBUTE-BASED ENCRYPTIONS AND FORMAL VERIFICATION OF LATTICE-BASED CRYPTOGRAPHY
2019199 pages ; Since the early works of Ajtai (STOC’96) and Regev (STOC’05), lattice-based cryptography has proven to be a powerful building block in cryptography. My research focuses on further exploring the expressive power of lattice-based cryptography, as well as formal verification of lattice-based cryptographic schemes.
