Abstract: The present disclosure provides a method for key-policy attribute-based encryption. The method includes receiving a message to be encrypted, a master public key, and a set of attributes. A random integer s is sampled between 1 and a prime integer p, where p is established by a pairing-friendly curve comprising three groups of two source groups and one target group. Every attribute in the set is hashed to a first source group of the pairing-friendly curve and multiplied by s to generate a set of attribute encodings. A target group element in the master public key is multiplied by s to generate a blinding factor. The message is masked with the blinding factor. A ciphertext is computed comprising the masked message, the set of attributes, the set of attribute encodings, and an encoding of s in a second source group of the pairing-friendly curve. The ciphertext is then outputted.

Abstract: The invention relates to systems, methods, network devices, and machine-readable media for encrypting and decrypting messages in a decentralized multi-authority attribute-based encryption (MA-ABE) scheme for a non-trivial class of access policies whose security is based in the random oracle model solely on the Learning With Errors (LWE) assumption. In some embodiments, any party can become an authority and there is no requirement for any global coordination other than the creation of an initial set of common reference parameters.

Abstract: The disclosure relates to generating a ciphertext of arbitrary and flexibly large size and ensures that an adversary learns little about the encrypted data, even if the decryption key later leaks, unless substantially the entire ciphertext is stored. Given that communication will be inconveniently large for the adversary to store, the incompressible ciphertexts and signatures can be sent and received with low storage requirements for the honest users. In such a setting, the honest users would not store the entire ciphertext or signature, but instead generate, send, and process the communication bit-by-bit in a streaming fashion.

Abstract: A broadcast network can use a pairing-based broadcast encryption scheme for N users with O(N1/3)-sized parameters. A pairing-based ciphertext-policy attribute-based encryption (CP-ABE) scheme for the class of degree 3 polynomials can be implemented with compact parameters. The public key, ciphertext and secret keys comprise O(n) group elements, where n is input length for the function. The constructions achieve adaptive security against unbounded collusions, and rely on the (bilateral) k-Lin assumption in prime-order bilinear groups.

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.
