Documentation

General Trusted Computing Base wrapper. This is an abstract generally designed class that enables any realization of TCB (either software or hardware). To each such TCB it would be needed to create appropriate TCBWrapper that would do all that stuff defined in this class.

methods

TCBWrapper(Eso *anEso, LogFile *aLogFile = NULL)
Costructor.

virtual ~TCBWrapper()
Destructor.

virtual Err Rollback(const TID tid)
Ability to be rollbacked.

virtual Err SaveFile( const ACID acid, const ID fid, const MsgField *ffid, const MsgField *keywords, const MsgField *data)
Stores file kept in "data" with ID "fid". "ffid", "keywords", "data" encrypted with TCBPubKey.

virtual Err DeleteFileByFileID(const ID fid)
Deletes a file.

virtual Err ComputeMAC(const ID fid, const MsgField *oAuth, MsgField **mac)
Computes MAC by finding a file and concatenating it with OAuth.

virtual Queue* GetFileHeadersByFAM( const ACID acid, const MsgField *fam, const GMessage *clientPubKey)
Finds all files matching the File Atribute Mask, and returns. their headers that include FinderFileID, FileSize. FAM encrypted by TCB Public Key.

virtual MsgField* GetFileByFinderFID( const ACID acid, const MsgField *ffid, const GMessage *clientPubKey)
Finds the file with "ffid", decrypts it, reencrypts it with "clientPubKey". and returns it as a MsgField.

virtual MsgField* DecryptByACPriv(const ACID acid, const MsgField *data)
Finds aproprite private key and returns decrypted "data".

virtual Err GenerateACKeys(ACID *acid, GMessage **acPubKey, GMessage **tcbPubKey)
Generates and stores AC keys (both AC and TCB).

virtual Err GetACPubKeys( const ACID, GMessage **acPubKey = NULL, GMessage **tcbPubKey = NULL)
Returns pub keys to ACID.

virtual Err RemoveACKeys(const ACID acid)
Removes AC keys (both AC and TCB).

virtual Err RefreshMasterKey()
Generates new Master Key and does all reencryption needed (table of ring keys)

virtual Err RefreshRingKeys()
Generates new Ring Keys and does all reencryption needed (table of files and Storage keys, table of certificates, table of transport keys)

TCBWrapper::TCBWrapper(Eso *anEso, LogFile *aLogFile)

TCBWrapper constructor. Initializes all ancestors.

Parameters:: anEso - pointer to owner of this class
aLogFile - log file for debugging messages
