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 ...

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....

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 ...
