  • DECENTRALIZED MULTI-AUTHORITY ATTRIBUTE-BASED ENCRYPTION FROM BILINEAR DIFFIE-HELLMAN ASSUMPTIONS
    Publication number: 20240080203
    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 access structures described by monotone LSSS under the decisional bilinear Diffie-Hellman assumptions. The construction can also be modified to obtain an MA-ABE scheme under computational bilinear Diffie-Hellman assumptions.

  • DECENTRALIZED MULTI-AUTHORITY ATTRIBUTE-BASED ENCRYPTION
    Publication number: 20230379153
    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.

  • SECURE MASSIVELY PARALLEL COMPUTATION FOR DISHONEST MAJORITY
    Publication number: 20230344628
    Abstract: Systems, methods, network devices, and machine-readable media disclosed herein include executing a secure algorithm for computing on a plurality of machines in a cluster by receiving a large input message and dividing the large input message into a plurality of initial input messages, computing an encryption of initial input messages, and evaluating a cluster computing circuit using a homomorphic encryption scheme.

  • TAMPER-RESISTANT DATA ENCODING SECURE AGAINST UNBOUNDED POLYNOMIAL SIZE ATTACK COMPLEXITY
    Publication number: 20230275741
    Abstract: Systems, methods, network devices, and machine-readable media disclosed herein include encoding data for storage or transmission by encoding the data according to a tamper-resistant data encoding scheme that renders the data secure against unbounded polynomial size attacks. The present disclosure further includes subsequently determining whether the data has been tampered with, and notifying a processor when the data has been modified or compromised.
