What is it about?
With an aim to propose a fully secure constant ciphertext length CP-ABE scheme, in this paper we discuss our attempt at extending the approach of Lewko et al. (in EUROCRYPT 2010). The scheme that we propose here, allows any subset of attributes of the secret key as a part of the ciphertext policy.

Why is it important?
It improves the existing scheme with sully secure and constant length approach. This reduces the time on receiver side with fixed number of pairing operations.
Perspectives
In this resource constrained environment, it is necessary to save time on decryption. Thus, in this research, we aim at achieving it with constant pairing operations.
