Abstract
Systems and methods for functional encryption systems that support regular languages and, thereby strings of arbitrary length, are provided. The disclosed systems and methods can encrypt data using public parameters and an arbitrary string. The arbitrary string can be included within the ciphertext as plaintext. A decryption key is generated that includes a representation of a regular language. The encrypted message can be decrypted only if the arbitrary string in the ciphertext is in the set of strings that comprise the regular language associated with the decryption key being used.
