Abstract
In a telecommunication network, individual network slices are provided for various uses and/or for various enterprise customers. A network subsystem such as a network slice comprises multiple components, such as routers, applications, virtual network functions, etc. Each component of the subsystem generates and provides a digital signature, such as a hash, based on state properties of the component that have been designated as being invariant. The signatures from the multiple components are then combined and hashed to form a subsystem signature. A chronological sequence of subsystem signatures is saved in a distributed ledger, which may use blockchain technology to protect against after-the-fact modifications to the saved signatures. A network threat may be detected by detecting situations in which the subsystem signature of a particular subsystem changes over time. A saved blockchain, containing the sequence of signatures, can be provided as historical evidence of network integrity.
