To mitigate these problems, we propose a practical solution that uses Identity-Based Encryption to simplify key management and enforce data confidentiality. Moreover, we devise an Identity-Based outsider anonym
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...
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....
The possibility and impossibility of tight security proofs has been considered for many primitives, including symmetric encryption [29, 31, 36], public-key encryption [3, 5, 24, 32], (hierarchical) identity-based encryption [11, 16], digital signatures [22, 23, 32, 33, 37, 43, 45, 47...
