Multi-functional Attribute Based Encryption from Lattices [PDF]
Jisuanji kexueAttribute based encryption from lattices has the property of resisting quantum attacks,and achieves fine-grained access control of attributes by cleverly embedding access control policies into ciphertext or keys.However,due to the inherent weaknesses of ...

Efficient algorithms for pairing-based cryptosystems [PDF]
, 2002 We describe fast new algorithms to implement recent cryptosystems based on the Tate pairing. In particular, our techniques improve pairing evaluation speed by a factor of about 55 compared to previously known methods in characteristic 3, and attain ...

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.

Practical identity-based key agreement for secure communication in sensor networks [PDF]
, 2009 Despite much research effort key distribution in Wireless Sensor Networks (WSNs) still remains an open problem. In this paper we address this issue by proposing a simple identity- based key agreement scheme. Our protocol uses Identity-Based Cryptography (
