Identity-based encryptionOnline Social Networks (OSNs) constitute vital communication and information sharing channels. Unfortunately, existing coarse-grained privacy preferences insufficiently protect the share
We present an Identity Based Encryption (IBE) system that is fully secure in the standard model and has several advantages over previous such systems – namely, computational efficiency, shorter public parameters, and a “tight” security reduction, albeit to a stronger assumption that depends on t...
We propose a leakage-resilient signature scheme in the continual leakage model that is based on a well-known identity-based encryption scheme by Boneh and Boyen (Eurocrypt 2004). The proposed signature scheme is the most efficient among the existing schemes that allow for continual leakage. Its ...
Threshold attribute-based encryption (thABE) is a variant of identity identity-based encryption which views identities as sets of descriptive attributes. If a thABE ciphertext c is computed for a set om of attributes, then, to decrypt c, a user must have keys associated with a sufficiently ...

a novel way. We formally prove all our security claims under common trust and hardness assumptions. At the core of Epoque lies an efficient identity-based encryption (IBE) scheme with blazingly fast master-key decryption. It is the component that makes the efficient tallying of ...
We wish to find K-1 (the inverse of K), such that K× K-1 = I (mod 26), where I is the identity matrix. The following formula tells us how to find K-1 given K:where d× d-1 = 1(mod 26), and adj(K) is the adjugate matrix of K....

In Ciphertext-Policy Attribute-Based Encryption (CP-ABE), a user’s decryption key is associated with attributes which in general are not related to the user’s identity, and the same set of attributes could be shared between multiple users. From the decryption key, if the user created a ...
