Identity-based Encryption Resilient to Master Key Leakage
YU Qi-hon · Science Technology and Engineering · 2014
In recent years,various side channel attacks have caused leakage of secret information of different cryptographic systems,so cryptography researchers have raised the research upsurge of leakage-resilient cryptographic schemes. An identity based encryption is presented which can resist the master secret key leakage. The correctness of the program is proved. The security of the scheme is obtained based on DBDH assumption. The performance of leakage-resilient is analyzed via the theory of entropy. The relative leakage rate of main secret key can almost reach 1.
