Adaptively Secure and Succinct Functional Encryption: Improving Security and Efficiency, Simultaneously
ADVANCES IN CRYPTOLOGY - CRYPTO 2019, PT III, pp. 521-551, 2018.
Functional encryption (FE) is advanced encryption that enables us to issue functional decryption keys where functions are hard-wired. When we decrypt a ciphertext of a message m by a functional decryption key where a function f is hardwired, we can obtain f(m) and nothing else. We say FE is selectively or adaptively secure when target mes...More
