Esquema de Estruturação SbC-EC para Log Seguro

Sérgio CâmaraLuci PirmezLuiz F.R.C. Carmo

Secure log schemes ensure detection of possible attacks against audit logs located in devices under an unprotected environment. This paper describes the structure scheme SbC-EC for secure logging, suitable for storage and network communication constrained devices, presenting two new features: Split by Category and Entry Compaction. We also describe the SbC-EC MAC secure log scheme, which implements the new proposed structure along with symmetric cryptography primitives and the FssAgg authentication scheme for protecting the log files. SbC-EC MAC presents a storage gain in comparison to other existing symmetric secure log schemes.
