Generic conversions from CPA to CCA without ciphertext expansion for threshold ABE with constant-size ciphertexts
CCA security is desirable when designing encryption schemes because it captures active attackers. One efficient approach for achieving CCA security is to use generic conversions. We first design a CPA secure scheme, and then transform it into a CCA secure scheme using the Fujisaki-Okamoto technique...
