Abstract
The present disclosure relates to a computerized method and system for message encryption in a multi-user setting. The method involves receiving a message of arbitrary length for each user, storing the message in a computerized data store, and executing a setup to generate a master secret and public keys. A random variable is generated, and a function is defined based on this variable. A second secret is derived using a functional encryption scheme, resulting in a derived secret. The message is encrypted by generating a first random string, a second partially random string, and a ciphertext. The system also includes a method for decrypting the encrypted message, processing the derived secret and ciphertext to derive a string, and deriving a plaintext message from this string.
