Abstract

Systems, methods, and instrumentalities are disclosed for integrity protecting log entries generated from a first unit in a distributed system. For example, a first secret key may be received or obtained from a central management system and storing the first secret key in non-volatile memory. A second secret key may be calculated where the second secret key may be shared with a plurality of units within the same local communication domain as a unit using a secure key calculation. The second secret key may further be stored in volatile memory. The first and second keys may be used to calculate a first secret integrity protection key and a first broadcast encryption key. A security sensitive log entry may be generated and may be protected using the first integrity key and the first broadcast encryption key. The log entry may be broadcast to the plurality of units within the domain.
