Abstract
This invention relates to a system for recovering access to a cryptocurrency wallet on a remote server. It introduces a wallet control apparatus, method, and system for registering a new cryptographic secret at a wallet hosted in a trusted execution environment on a server. The apparatus generates a new cryptographic secret for the wallet, retrieves a second cryptographic secret from another remote server after authenticating the wallet owner, and uses this second secret to sign a control instruction. This instruction is sent to the server to register the new cryptographic secret, enabling secure wallet control.
