Abstract
Methods and systems for authenticating data processing systems throughout a distributed environment without user intervention are disclosed. To authenticate data processing systems without user intervention, a system may include a network core and one or more data processing systems. A previously established root of trust between the network core and a data processing system may be lost and the network core may attempt to re-authenticate the data processing system using shared knowledge. The shared knowledge may be based on data obtained from the data processing system and an inference generated by a twin inference model. The network core may provide the data processing system with a security questionnaire based on the shared knowledge and the data processing system may use the twin inference model to respond to the security questionnaire. If the answers to the security questions are considered accurate, the data processing system may be re-authenticated.
