Abstract: A computing system cryptographically generates an intermediate message authentication code as a function of the message and a cryptographic key assigned to a first party. The computing system also generates a first instance of an aggregate message authentication code corresponding to the message by combining the intermediate message authentication code with one or more other intermediate message authentication codes of one or more second parties. Each code of the one or more other intermediate message authentication codes is cryptographically generated as a function of the message and individual cryptographic key assigned to each of the one or more second parties.

Abstract: A computing system determines a maximum field size for a field containing values of quantized versions of a weight matrix, an input data matrix, and a bias matrix and determines a weight upper bound of scaling factors for the weight matrix based on values of the weight matrix, an input data upper bound of scaling factors for the input data matrix based on values of the input data matrix, and a bias upper bound of scaling factors for the bias matrix based on values of the bias matrix. The computing system also sets a weight scaling factor of the weight matrix, an input data scaling factor of the input data matrix, and a bias scaling factor for the bias matrix in two different cases: when the sum is less than or equal to the bias upper bound and when the sum is greater than the bias upper bound.

Abstract: Evolving function secret sharing is performed on a given function by multiple share parties, A dealer selects a random vector for each share party corresponding to an arrival order. The dealer generates an array of function shares for each share party of the set, each array including a function share based on the random vector corresponding to the share party and one or more function shares cryptographically generated based on the random vector corresponding to each previously-arrived share party. The dealer distributes an array of the function shares to each share party, wherein a first function share result resulting from a computation of a first function share on given input data and at least a second function share result resulting from a computation of a second function share on the given input data are combinable to yield a result of the given function executed on the given input data.

Abstract: A secret sharing scheme with yes and no shares and having a hidden access structure. The secret sharing scheme may include share generation in which yes shares and no shares are generated for, and distributed to, each party in the secret sharing scheme. In turn, upon an attempt to reconstruct the secret, participants in the reconstruction each provide a share, which is unknown to be a yes share or a no share to the other participants. The secret is only reconstructable if the shares used in the reconstruction include yes shares of a minimal authorized subset of the parties. However, prior to secret reconstruction, the access structure remains hidden and the participants in a reconstruction are unaware of the character of the shares provided by other participants in the reconstruction attempt.
