Cryptanalysis of a certificateless aggregate signature scheme [PDF]

, 2016
Recently, Nie et al. proposed a certificateless aggregate signature scheme. In the standard security model considered in certificateless cryptography, we are dealing with two types of adversaries.

CLKS: Certificateless Keyword Search on Encrypted Data [PDF]

, 2015
. Keyword search on encrypted data enables one to search key-word ciphertexts without compromising keyword security. We further in-vestigate this problem and propose a novel variant, dubbed certificateless keyword search on encrypted data (CLKS).
