A Hierarchical Identity Based Encryption (HIBE) system is anonymous if the ciphertext reveals no information about the recipient’s identity. create it. While there are multiple c...

We describe an identity based signature scheme that uses biometric information to construct the public key. Such a scheme would be beneficial in many repudiation situations for e...

In this paper we construct two new fuzzy identity-based encryption (IBE) schemes in the random oracle model. Not only do our schemes provide public parameters whose size is indepe...

Abstract. We propose a variant of the “bonsai tree” signature scheme, a latticebased existentially unforgeable signature scheme in the standard model. Our construction offers ...

Anonymous hierarchical identity based encryption (HIBE) is an extension of identity based encryption (IBE) that can use an arbitrary string like an e-mail address for a public key...
