摘要

In this study, we propose a new ID-based beta cryptosystem scheme secure under selective identity adaptive chosen ciphertext security (IND-sID-CCA) under assumption in the random oracle model. We demonstrate that our scheme outperforms the other existing schemes in terms of security, computational cost and the length of public key.
