Abstract: Examples are disclosed herein to implement remote authentication and passwordless password reset. An example server includes: at least one processor to forward executable instructions to a client device, the executable instructions, when executed at the client device, to cause the client device to: authenticate a user of an account based on a biometric authentication factor; obtain a local storage key by decrypting an encrypted local storage key with a cloud key obtained from a remote authentication server, the cloud key associated with the client device; decrypt a key bag with the local storage key, the key bag including a content encryption key and an encrypted credential encrypted with the content encryption key, the encrypted credential associated with the user; and decrypt the encrypted credential with the content encryption key to obtain a credential without the user supplying a master password associated with the account.

Abstract: In a method for secure cloud computing, a virtual machine (VM) associated with a client is executed at a computer within a trusted computing cloud. An image including state information of the VM is obtained; storage of the image is arranged; a freshness hash of the image is determined; and the freshness hash is sent to the client. Subsequently, at the same computer or at a different computer within the trusted computing cloud, the stored image may be retrieved; a freshness hash of the retrieved image may be determined; the freshness hash of the retrieved image may be sent to the client; and an indication may be received from the client verifying the integrity of the freshness hash of the stored image.

Abstract: A passwordless reset technique includes actions to receive a request for a password reset, wherein the request password reset is initiated at a first device, determine that the first device is a trusted device, authenticate the user in order to obtain a cloud key from a network device, wherein the cloud key is associated with the first device, derive a key encryption key using the cloud key, decrypt a local storage key using the key encryption key, decrypt a local storage using the local storage key to obtain a content encryption key, obtain a new password via user input, re-encrypt the content encryption key, and transmit it to the network device, derive a new authentication token using the new password, and transmit the new authentication token to the network device.

Abstract: A technique allows for transparently managing, suspending, restoring, sharing, limiting and migrating user sessions on a device without having access to user credentials. A user may automatically log in and out of each or all their online accounts instantaneously and, in doing so, the user may share sessions without sharing passwords across client devices as well as with other authenticated and authorized users. Sharing may be done in a secure manner with the initiating-user being able to restrict shared session rights, as well as being able to remove access to each of the shared sessions.

Abstract: Techniques are disclosed for providing an authentication service that performs authentication of users on behalf of a relying party. The authentication service receives authentication requirements from the relying party and compares those requirements with authentication capabilities of the user and user equipment. If the authentication requirements are met, the authentication service may perform authentication using the corresponding authentication factors. If the available authentication factors are insufficient or the user fails authentication using the authentication factors used by the authentication service, the relying party may be notified that authentication failed. Upon successful authentication, the authentication service notifies the requiring party that the user has been authenticated.

Abstract: A method for producing a semiconductor device is provided. A growth substrate having a first side and an opposite second side is provided. At least one electronic component is produced by depositing and/or structuring at least one layer on the first side of the growth substrate, said layer containing or consisting of at least one compound semiconductor. The first side of the electronic component that is opposite the first side of the growth substrate is connected to a support. The growth substrate is removed. The support has at least one feed-through and/or at least one conductor track, which is connected to at least one terminal contact of the electronic component. Alternatively or in addition, a semiconductor device produced in this way and a support having such a semiconductor device may be provided.

Abstract: The present disclosure relates to receiving a request for recovery of an account associated with a user, sending a CAPTCHA challenge to a user device associated with the user, receiving an answer to the CAPTCHA challenge and a confirmation code wrapped by an encryption key derived from a provisional master password, sending a notification of the request for recovery to one or more trusted entities associated with the user, and receiving a confirmation of the request from one or more of the trusted entities. The confirmation includes a recovery token associated with the particular trusted entity and an encrypted confirmation code.

Abstract: A circuit arrangement with at least a source contact (7), a gate contact (6), and a Schottky-Reverse contact (2), which is embodied as a Schottky-contact above a transistor channel and connected to the source contact such that in a return operation electrons can flow from a drain contact (5, 5.1, 5.2) via the Schottky-Reverse contact to the source contact. The circuit arrangement includes at least two transistor sections (A, A?, B, B?), with a first of the transistor sections (A, A?) including the Schottky-Reverse contact and a second of the transistor section (B, B?) being embodied without the Schottky-Reverse contact. The two transistor sections (A, A?, B, B?) are arranged alternating and embodied such that at least in a forward operation electrons can flow in a transistor channel from a source contact (7) to the drain contact (5, 5.1, 5.2), circumventing an area of influence (12) of the Schottky-Reverse contact.
