The system further includes a memory and a refresh server. The system is configured, for each of successive new time periods in operation of the protocol, to perform a refresh operation wherein: the refresh server retrieves the state information from the memory, generates a new set of communication keys, and sends the state information and new set of keys to the machine management server; the machine management server configures a new virtual machine for implementing the protocol, whereby the new virtual machine receives the new set of keys and state information sent by the refresh server; and the new virtual machine assumes operation as the current virtual machine for the new time period and stores state information for that time period in the memory."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Server systems for distributed cryptographic protocols","description":"A server system for implementing a distributed cryptographic protocol includes a machine management server which comprises a current virtual machine configured to implement the protocol using a set of","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9641325","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
