Abstract
A system and method for protecting streams in a mixed infrastructure includes determining processing elements that are to access a data stream in a stream processing environment and determining a security level for each processing element. Keys are generated per stream per processing element in accordance with the security level. The keys are associated with processing elements in an access control list in a location accessible by producing and consuming processing elements. The stream is decrypted for processing using keys released upon authenticating processing elements in accordance with the access control list. At security boundaries, the stream is re-encrypted in accordance with a next processing element.
