As part of my ongoing research into the Edward Snowden documents, I have found and added an additional document to the Canadian SIGINT Summaries. The Summaries include downloadable copies of leaked Communications Security Establishment (CSE) documents (and those pertaining to CSE activities), along with summary, publication, and original source information. CSE is Canada’s foreign signals intelligence agency and has operated since the Second World War.

Documents were often produced by CSE’s closest partners which, collectively, form the ‘Five Eyes’ intelligence network. This network includes the CSE, the National Security Agency (NSA), the Government Commsiunications Headquarters (GCHQ), Australian Signals Directorate (ASD), and Government Communications Security Bureau (GCSB).

All of the documents are available for download from this website. Though I am hosting the documents they were all first published by another party. The new documents and their summaries are listed below. The full list of documents and their summary information is available on the Canadian SIGINT Summaries page.

This document came to my attention as part of analysis of NSA-Japanese signals intelligence cooperation. The Canadian-centric aspect of the document concerns the number of High Frequency Direction Finding sites that were, as of 2005, operated by Canada.

CROSSHAIR — Foreign Partners Filling HF/DF Gaps for the US

Summary: This brief article identifies the number of second-party High Frequency Direction Finding (HF/DF) resources, along with contributing third-parties, which collectively compose the CROSSHAIR network with US government assets. The CROSSHAIR covername refers to a project that consolidated all US Service Cryptologic Element (SCE) HF/DF resources and enables data operability with partners.

Canada possessed four sites at time of writing, Great Britain six, and Australia and New Zealand one each. Third-parties, including Austria, Denmark, Ethiopia, Hungary, Israel, India, Italy, Japan, Jordan, Korea, Netherlands, Norway, Pakistan, Saudi Arabia, Sweden, and Taiwan, also shared with the NSA and, in some cases, directly with one another. The NSA recognizes, in this document, that without the third-party collaborators the NSA would lack a world-wide network for Direction Finding.
