Abstract
A node includes processing circuitry configured to encrypt first network data including a first tenant identifier using a first cryptographic key to generate first encrypted data and anonymize the first encrypted data to generate anonymized data where the anonymizing of the first encrypted data includes segmenting the first encrypted data and the anonymizing of the first encrypted data preserving relationships among the first network data associated with the first tenant identifier, encrypt the anonymized data using a second cryptographic key to generate encrypted anonymized data, transmit the encrypted anonymized data, at least one analysis parameter, at least one security policy and instructions to analyze the encrypted anonymized data using the at least one analysis parameter, the at least one security policy and the second cryptographic key, receive analysis data resulting from the analysis of the encrypted anonymized data, and determine verification results from the received analysis data.
