Abstract: A system for homomorphically generating rotation keys for use in homomorphic computation in association with a client, and a server coupled to the client machine over a network. Client-side code executes in the client to derive a set of Learning With Errors (LWE) ciphertexts from a secret key polynomial, the secret key polynomial having a set of coefficients. Each LWE ciphertext is derived from a coefficient of the secret key polynomial and having a single coefficient. The client-side code transmits the set of LWE ciphertexts to the server. Server-side code receives the set of LWE ciphertexts and processes them into a ring variant (R-LWE) ciphertext homomorphically to generate the one or more rotation keys. The R-LWE ciphertext encrypts a polynomial having the set of coefficients of the secret key polynomial; a given rotation key corresponds to rotated coefficients of that polynomial. The generated rotation keys are useful for FHE computation.

Abstract: Device-implemented methodology for enabling and/or performing crypto-erase via internal action and/or external action in a Key per IO-enabled system. In various approaches, crypto-erasure of the data stored in a Key per IO scheme is enabled by implementing an internal key, which is combined with an external key to generate a media encryption key, which is in turn used to encrypt/decrypt data. By restricting access to the internal key, destruction of the internal key and all media encryption key(s) created using the internal key, renders the data crypto-erased, and thus unrecoverable.

Abstract: In a method for intelligently executing predictive simulator, a processor may input a previous input vector of conditions for a predictive simulator collected at a first time into a machine-learning (ML) model. A processor may input a current input vector of conditions for the predictive simulator collected at a second time into the ML model. A processor may determine using the ML model, a binary similarity index. The binary similarity index represents a prediction of similarity between a first output from the predictive simulator based on the previous input and a second output from the predictive simulator based on the current input.

Abstract: A signal-analysis-based process for detecting and correcting power feeds is provided. The process includes obtaining voltage waveform data for power feeds connected to a system, and determining for the power feeds, using the obtained voltage waveform data, at least one respective signal characteristic. Further, the process includes comparing the respective signal characteristics of the power feeds to ascertain at least one signal characteristic difference between the power feeds.

Abstract: A computer-implemented system and method operate an automatic and adaptive animal behavioral system. The system receives user configuration and feedback, and generates a training set based on online animal behavior patterns and received user feedback. The system trains one or multiple models based on the training set, if the training set is sufficiently large. It then validates the models, and provides system generated classifications and action types and levels for animal's behavior patterns, if the models' accuracy rate is above a threshold.
