Digital Message Confidentiality

点击翻译按钮获取中文摘要

Confidentiality is a fundamental building block of modern digital network systems. Confidentiality focuses on the ability of digital systems to prevent unintended recipients from understanding exchanged messages. Traditional short-term encryption keys rely on expensive key generators and while traditional short-term encryption has shown resilience to wiretapping and passive listening, it has been shown that there are risks with poor key management. This has led the National Institute of Standards and Technology (NIST) to renew its recommendations to fix key management vulnerabilities. An alternative approach to reinventing encryption is to add additional layers to traditional security systems leading to multi-layer-encryption or multi-fencing. The introduction of Network Coding has led the research community to develop novel approaches to tackle persistent security challenges. Different from routing, network coding applies a strategy of coding and forwarding. As a result, the content encapsulated in a packet is not the raw message but an alteration or transformation. An intruder cannot resolve the raw message from the intercepted packets given that he doesn't possess a prior-knowledge of the coding scheme and/or sufficient packets. In the quest to remain ahead of the ever growing security attack mechanisms, Juniper is interested in utilizing subspace network coding to remain ahead of ever growing security threats. Juniper Networks is a world leader in network equipment and software that is extending its interest into security and confidentiality of information.
