Abstract: Executing the operations of an arithmetic circuit by using a hybrid strategy that employs both fully homomorphic encryption (FHE) methods and multi-party computation (MPC) methods. In order to utilize this hybrid strategy, an arithmetic circuit is split into multiple partitions (at least two), and each partition is assigned to be executed using FHE methods or MPC methods. Finally, this hybrid strategy is utilized in a manner that automatically takes into account CPU and network utilization costs.

Abstract: An example system includes a processor to receive, at a setup or sign-up, a first cipher including a biometric template transformed using a first transformation and encrypted using a secret key, a second cipher including a security vector encrypted using the secret key, a third cipher including the biometric template transformed using a second transformation and encrypted, and a fourth cipher including an encrypted second security vector. The processor can receive, at a runtime or sign-in, a fifth cipher and a sixth cipher. The processor can verify that the fifth cipher includes a second biometric template transformed using the first transformation and encrypted using the secret key and that the sixth cipher includes the second biometric template transformed using the second transformation by testing a format attribute of the transformation functions using comparisons of inner products.

Abstract: A method, apparatus and product performing feature vector aggregation for malware detection. Two sets of measurements produced by a two dynamic analyses of an examined program are obtained, wherein the two dynamic analyses are performed with respect to the examined program executing two different execution paths.
