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.

Abstract: Providing security for one or more network flows may include a security deployment node decomposing one or more virtual security appliances (265) of a logical security architecture (255) into security modules (310). The security deployment node orders the security modules (310) into a sequence (320) that implements a selected workflow pattern (400). The selected workflow pattern (400) may be selected from a workflow pattern database, and may define the security to be provided for a flow, for example, according to known best practices. The sequence (320) is then divided into segments (330), and the segments (330) are assigned to different groups (220) of network nodes (230) in a network (200). For each segment (330), an assignment of each security module (310) in the segment (330) to a network node (230) within the group (220) to which the segment (330) is assigned is computed. The network (200) is then configured according to the assignments.
