Abstract
Streams applications may decrypt encrypted data even though the decrypted data is not used by an operator. Operator properties are defined to permit decryption of data within the operator based on a number of criteria. By limiting the number of operators that decrypt encrypted data, the anonymous nature of the data is further preserved. Operator properties also indicate whether an operator should send encrypted or decrypted data to a downstream operator.
