Abstract
A lawful interception administrative function (LI ADMF) provides a virtual network function (VNF) implemented (i.e. implemented in a cloud infrastructure) LI intercept access point (IAP) only with one-way encrypted targets instead of clear-text targets while keeping the lawful interception triggering capability of the IAP unaffected. The ADMF, being external to the cloud infrastructure in which the IAP is running, executes hashing of targets before the targets are provided to the IAP. The IAP will never receive targets in clear text and thereby greatly reducing the LI security risks.
