Latest Patents

Metsala holds a patent for a "Secured network architecture." This invention provides a secure storage solution for an X.509v3 digital certificate. The architecture ensures that ports of a first and second apparatus are mutually authenticated using 802.1X based authentication and 802.1AR certificates. Traffic types are effectively divided by an operator-configurable selector function into user plane, control plane, synchronization plane, and management plane traffic types. For Ethernet transport, a virtual port is created for each traffic type, with a different MACsec secure connectivity association established for each virtual port. Additionally, an operator-programmable security policy is maintained for each traffic type, ensuring robust security measures. For IP transport, an IPsec security association is created for each traffic type, with TLS support enabled for compatibility with network management traffic. The system also features a port that is repeatedly re-authenticated by an operator-definable timer value.
