METHODS, SYSTEMS, AND COMPUTER READABLE MEDIA FOR SELECTIVE INTER-PUBLIC LAND MOBILE NETWORK (PLMN) SECURITY HANDSHAKE VALIDATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 17825523 titled 'METHODS, SYSTEMS, AND COMPUTER READABLE MEDIA FOR SELECTIVE INTER-PUBLIC LAND MOBILE NETWORK (PLMN) SECURITY HANDSHAKE VALIDATION

Simplified Explanation

The abstract describes a method for validating the security handshake between different Public Land Mobile Networks (PLMNs).

  • The method involves a Secure Edge Protection Proxy (SEPP) receiving a security handshake request message from another PLMN.
  • The SEPP checks if the requesting PLMN is trusted by looking it up in a trust relationship database.
  • If the requesting PLMN is not trusted, the SEPP performs a security handshake validation procedure on the request message.
  • If the request message fails the validation procedure, the SEPP performs a network protective operation to ensure security.


Original Abstract Submitted

A method for selective inter-PLMN security handshake validation includes receiving, at a SEPP, a first inter-PLMN security handshake request message. The method further includes performing, by the SEPP and in an SEPP trust relationship database, a lookup to determine whether the first inter-PLMN security handshake request message originates from a trusted SEPP. The method further includes determining that the first inter-PLMN security handshake request message does not originate from a trusted SEPP, and, in response, performing, by the SEPP, an inter-PLMN security handshake validation procedure on the first inter-PLMN security handshake request message. The method further includes determining that the first inter-PLMN security handshake request message fails the inter-PLMN security handshake validation procedure, and, in response, performing a network protective operation.
