Conditional Identity-Based Broadcast Proxy Re-Encryption and Its Application to Cloud Email Abstract Recently, a number of extended Proxy Re-Encryptions (PRE), e.g. Conditional (CPRE), identity-basedPRE (IPRE) and broadcast PRE (BPRE), have been proposed for flexible applications. By incorporating CPRE, IPRE and BPRE, this paper proposes a versatile primitive referred to asconditional identity-based broadcast PRE (CIBPRE) and formalizes its semantic security. CIBPRE allows a sender to encrypt a message to multiple receivers by specifying these receivers’ […]

An Efficient File Hierarchy Attribute-Based Encryption Scheme in Cloud Computing Abstract Ciphertext-policy attribute-based encryption (CP-ABE) has been a preferred encryption technology to solve the challenging problem of secure data sharing in cloud computing. The shared data filesgenerally have the characteristic of multilevel hierarchy, particularly in the area of healthcare and the military. However, the hierarchy structure of shared files has not been explored in CP-ABE. In this paper, […]
