Inter-domain traffic engineering solutions based on the Path Computation Element (PCE) architecture are exposed to information confidentiality issues between network carriers. Licit PCE Protocol (PCEP) request sequences may hide a malicious intention to discover critical intra-domain information through correlations among replies. This work presents an innovative anomaly-based statistical approach based on the Sequential Hypothesis Testing (SHT) aiming to detect malicious utilization of PCEP by… CONTINUE READING
