The Imapct of the common Data Security Architecture (CDSA) on Telemetry Post Processing Architectures

摘要

It is an increasing requirement that commercial satellite telemetry dataproduct be protected from unauthorized access during transmission to ground stations. While the technology (cryptography) to secure telemetry data product is well known, the software infrastructure to support such security is costly, and customized. Further, many software packages have difficulty interoperating. The Common Data Security Architecture [1][2][3] (originally proposed by the Intel Crporation, and now adopted by the Open Group), is a set of common cryptographic [4] and public key infrastructure (PKI) application programming interfaces (APIs) which will facilitate better cryptographic interoperability as well as making cryptographic resources more readily available in telemetry post processing environments.
