Many of our customers responded with the need to share sensitive data with approved collaborators.  We are excited to announce the release of  _ultra 1.2 to support sharing of encrypted data sets without decryption through single key exchange. This capability is particularly useful in big data collaboration because the compute overhead to share data is independent of its size. Key exchange is accomplished in constant time which means the shared encrypted data set is immediately available for computation. 

Keyword search is enabled on shared data by utilizing a key exchange system based on standard public and secret key cryptography. The _ultra encrypted key architecture allows applications to manage information in vulnerable cloud or on-premise environments while keeping sensitive data unreadable to the infrastructure provider and host.
