Preserving the privacy of electronic medical records (EMRs) is extremely important especially when medical systems adopt cloud services to store patients’ electronic medical records. Considering both the privacy and the utilization of EMRs, some medical systems apply searchable encryption to encrypt EMRs and enable authorized users to search over these(More)
Revocable hierarchical identity-based encryption (RHIBE) is a good candidate encryption for secure wireless communications. Its dynamic user management through the hierarchical key generation and revocation is efficient. Most existing RHIBEs are bounded which have to fix the maximum hierarchical depth of users at setup. In this paper, we propose the first(More)
For Securing BGP Protocol, this paper proposes an identity-based private key infrastructure (iPKI) for managing self-attested IP (sIP) addresses. An sIP address endows the current IP address self-attested characteristic, which does not rely on any credential based PKI. Based on the sIP address, we design the In-Band Self Origin Verification (IBSOV) protocol(More)
