Abstract: Provided are a device and method for training a neural network. The method includes generating a candidate solution set by modifying a candidate solution which represents a basic neural network model in a variable-length string form, acquiring first candidate solutions by performing architecture variation-based unsupervised learning with a plurality of candidate solutions selected from the candidate solution set, selecting a neural network model represented by a first candidate solution which satisfies targeted effective performance as a first neural network model, acquiring second candidate solutions by performing selective error propagation-based supervised learning with the first neural network model, and selecting a neural network model represented by a second candidate solution which satisfies the targeted effective performance as a final neural network model.

Abstract: A method and an apparatus for device security verification utilizing a virtual trusted computing base are provided. The validity of a key for decryption is verified by a secure memory loader running on a processor of a device after booting of the device which is a computing device, and if the key is valid, encrypted firmware stored in a memory of the device is decrypted using the key to verify the confidentiality of the firmware. Then, the security memory loader verifies the authentication and integrity of the firmware by comparing a signature value generated for the decrypted firmware with an existing signature value.
