Secure certificate-based encryption against entropy and key leakage
YU Qi-hon · Jisuanji yingyong yanjiu · 2014
Some attacks which can get some key information from the cryptosystem break the security of the entire cryptosystem. How to design secure cryptosystems is getting more and more attention of the researchers in cryptography community. The paper presented an encryption scheme which was based on certificate-based encryption. It designed a certificate-based hash proof system which contained a key encapsulation algorithm. Then it used this key encapsulation algorithm which was combined with an extractor to encrypt a symmetric encryption key. The scheme was resilient to entropy and secret key leakage. It slso gare the proof of security and analysis of the capability resilient to entropy and secret key leakage.
