Computation using lattice-based cryptography
Publication/Patent Number: US10897357B2 Publication Date: 2021-01-19 Application Number: 15/945,163 Filing Date: 2018-04-04 Inventor: Del, Pino Rafael   Lyubashevsky, Vadim   Neven, Gregory   Assignee: International Business Machines Corporation   IPC: H04L9/28 Abstract: The invention relates to a method for performing a multi-party electronic computation using a plurality of evaluating computer systems. The cryptographic security of the multi-party computation is implemented using lattice-based cryptography. Each evaluating computer system receives from each user of a plurality of users an individual input share of an input chosen by the respective user. Furthermore, each evaluating computer system receives from the user a commitment to the received individual input share and an opening information. Each evaluating computer system checks the commitments received to the individual input shares and generates a first lattice-based zero-knowledge proof that all the commitments received are valid commitments to input shares. Each evaluating computer system publishes the first lattice-based zero-knowledge proof. Thus, a verifier may be enabled to verify that all commitments are valid commitments to input shares.

Publication/Patent Number: WO2020015525A1 Publication Date: 2020-01-23 Application Number: 2019094495 Filing Date: 2019-07-03 Inventor: Tan, Yin   Wu, Teng   Assignee: Huawei Technologies Co., Ltd.   IPC: H04L9/28 Abstract: A method for verifying a property of plaintext using ciphertext is disclosed. In an embodiment, a computing device may receive the ciphertext at a trusted execution environment (TEE) of the computing device. The TEE may decrypt the ciphertext to generate the plaintext using a private encryption key of an encryption key pair. The encryption key pair comprises a public encryption key and the private encryption key. The TEE may generate a digitally signed validation result by encrypting the validation result using a private signing key of a signing key pair. The signed key pair comprises a public signing key and the private signing key. The private key is retrieved from secure memory of the computing device, and the secure memory may only be accessible by the TEE. The computing device may then transmit the digitally signed validation result.
