Comments Off on Captcha as Graphical Passwords-A New Security Primitive Based on Hard AI Problems
Posted in: .Net, IEEE 2017
Captcha as Graphical Passwords—A New Security Primitive Based on Hard AI Problems Many security primitives are based on hard mathematical problems. Using hard AI problems forsecurity is emerging as an exciting new paradigm, but has been under-explored. In this paper, we present a new security primitive based on hard AI problems, namely, a novel family […]

Comments Off on Key-Aggregate Cryptosystem for Scalable Data Sharing in Cloud Storage
Posted in: .Net, IEEE 2017
Key-Aggregate Cryptosystem for Scalable Data Sharing in Cloud Storage Data sharing is an important functionality in cloud storage. In this paper, we show how to securely, efficiently, and flexibly share data with others in cloud storage. We describe new public-keycryptosystems that produce constant-size ciphertexts such that efficient delegation of decryption rights for any set of […]
