....be somewhere in the code, it is thus possible to recover it. If we try to develop new business models such as pay per use, running time, pay per print, we need a secure place where to store those values (number of prints, amount, Some people tried to implement it in software [SV01, VMS02] although a minimal security is di#cult to achieve. Basically, if these values are not stored in a secure hardware device, it is very easy to make a bit copy of the hard disk, use the program, replace the contents of the hard disk with the copy made. After that, the protection system is sure to ....

....user data after data corruption has been detected. Since backup creation is a relatively heavy weight operation, it is typically performed infrequently and, therefore, a large number of updates can be lost during a backup restore. Secure database systems such as the Trusted Database (TDB) [10, 25] and GnatDb [24] combine the mechanisms for implementing secrecy and tamper detection described in Section 4.3 with fine grained recovery based on transactions. The database system recovers a consistent database state after a fail stop fault by rolling back all partial updates. The design of both ....
....a backup restore is a controlled form of the replay attack) Despite the security features TDB provides over other embedded database systems, its performance is quite good. TDB outperforms a popular embedded database system, the BerkeleyDB, on the TPC B benchmark on average by a factor of 1. 8 [25]. The code footprint of the ChunkStore on the x86 is 142 KB, the Backup Store 22 KB and the rest of the modules 86 KB. 8 4.4.2 GnatDb GnatDb s architecture consists of two layers: the Secure Device and the Store. The Secure Device implements pageoriented access to a virtual device that provides ....
