AUTOMATICALLY GENERATE ATTRIBUTES AND ACCESS POLICIES FOR SECURELY PROCESSING OUTSOURCED AUDIT DATA USING ATTRIBUTE-BASED ENCRYPTION

摘要

Methods, systems, and computer-readable storage media for secure storage of and selective access to encrypted audit data. Implementations include actions of receiving a set of audit data in response to occurrence of an incident, determining a set of static audit data and a set of dynamic audit data based on the set of audit data, encrypting items in the set of static audit data using a first attribute-based encryption scheme to provide a set of encrypted static audit data, and items in the set of dynamic audit data using a second attribute-based encryption scheme to provide a set of encrypted dynamic audit data, and transmitting the set of encrypted static audit data and the set of encrypted dynamic audit data to an off-premise database for storage and selective access.
