NuCypher’s revolutionary big data encryption layer enables organizations to use military-strength encryption to protect large, distributed data sets in the cloud or on-premise, without sacrificing functionality or performance. It’s the latest advance in the rich history of cryptography and encryption.
In Roman times, messengers carried encrypted communications as a way to send information. A second messenger traveled separately, carrying the decryption scheme. This separation of duties protected the underlying message in the event of capture or interception. While the transmission mechanism has changed, the core challenge remains.
In today’s enterprise, cryptography protects the secrecy and integrity of data. But traditional cryptographic schemes do not scale well. They aren’t suited for big data platforms where many users process massive amounts of data on distributed servers. Designed for structured relational databases, legacy encryption products lack the ability to scale in dynamic, petabyte-scale, distributed computing architectures. None are optimized for big data platforms and distributed file systems like HDFS. And certainly not for cloud environments.
When it comes to securing big data in the enterprise, existing encryption solutions are insufficient in yet more ways. Hadoop’s transparent data encryption (TDE) lacks basic key rotation capabilities, forcing manual, time-consuming workarounds. This makes it difficult to fit into existing enterprise security infrastructures and comply with standards requiring key rotation such as PCI. It also creates security risks when used in cloud environments, exposing secret keys to the cloud provider.
