原始语种摘要: Abstract(#br)Searchable encryption enables private keyword search over encrypted data held on an untrusted cloud. However, existing searchable encryption schemes promise search efficiency at the expense of additional privacy leakage or expensive storage overhead. Intel SGX is a promising tool to allow efficient and private keyword search. However, since the size of enclave created by SGX is limited, frequent sensitive-page swaps between the enclave and the untrusted memory cause severe performance degradation for large datasets. Moreover, SGX does not protect against access pattern leakages which are vulnerable to statistical inference attacks.(#br)To overcome the above problems, we present Pbsx, an efficient private boolean searchable encryption scheme using Intel SGX. Pbsx firstly...
