Group-Based Proxy Re-encryption Scheme
Recently, proxy re-encryption scheme received much attention. In this paper, we propose a proxy re-encryption used for divert ciphertext from one group to another. The scheme is bi...

Bounded CCA2-Secure Encryption
Abstract. Whereas encryption schemes withstanding passive chosenplaintext attacks (CPA) can be constructed based on a variety of computational assumptions, only a few assumptions a...

Verifiable Attribute Based Encryption
In this paper, we construct two verifiable attribute-based encryption (VABE) schemes. One is with a single authority, and the other is with multi authorities. Not only our schemes ...

Public Key Encryption with Keyword Search Based on K-Resilient IBE
An encrypted email is sent from Bob to Alice. A gateway wants to check whether a certain keyword exists in an email or not for some reason (e.g. routing). Nevertheless Alice does n...

Sequential Key Derivation Patterns for Broadcast Encryption and Key Predistribution Schemes
Abstract. We study two closely related primitives: Broadcast Encryption and Key Predistribution Schemes (KPS). Broadcast Encryption allows a broadcaster to broadcast an encrypted m...
