Abstract
A node including processing circuitry configured to: generate anonymized data based at least in part on a first cryptographic key and network data, calculate a coordination vector, generate initialized data based at least in part on the anonymized data, a second cryptographic key and the coordination vector, transmit the initialized data, the random vector, a security policy and instructions to analyze n iterations of the initialized data and the security policy using the random vector and the second cryptographic key, and receive results of the analysis of the n iterations of the initialized data and the security policy using the random vector and the second cryptographic key. The analysis of an m iteration of the n iterations correspond to an analysis of the initialized data with prefix preservation where the analysis of the remaining iterations of the n iterations fail to be prefixed preserved.
