Secure hybrid-indexed search for high efficiency over keyword searchable ciphertexts
We propose our high efficient Secure Hybrid Indexed Search (SHIS) scheme. We model semantic secure SHIS with universal transformations from PEKS and DE. We show the complexity of SHIS is much lower than PEKS and convergent. We universally extend SHIS by PKE schemes towards multiple-receiver applications.
