  • Publication number: 20250219821
    Abstract: A method for managing sessions with an application server via an identity management system is described. The method may include receiving, via an application protocol interface (API) of a cloud service of the identity management system, a first request associated with a first user for user access to an account of the application server. The API may transmit a second request for a secrets service to encrypt a password associated with the first user to a public key of a keypair. The API may receive a message including the encrypted password and forward the encrypted password to an end-client. The identity management system may establish a session on behalf of the first user for the account of the application server based on the end-client having access to a private key of the keypair.

  • Publication number: 20250210690
    Abstract: Disclosed is a solid electrolyte membrane, a method for manufacturing the same, and an all-solid-state battery including the same. More specifically, the solid electrolyte membrane includes a first solid electrolyte layer including a first solid electrolyte and a first fibrous binder and a second solid electrolyte layer including a second solid electrolyte and a second fibrous binder, stacked adjacent to each other, wherein the weight of the first fibrous binder relative to the total weight of the first solid electrolyte layer is less than the weight of the second fibrous binder relative to the total weight of the second solid electrolyte layer. Since the weight of a first fibrous binder included in the first solid electrolyte layer is less than the weight of the second fibrous binder included in the second solid electrolyte layer, the strength may be improved without lowering the ionic conductivity of the solid electrolyte membrane.
