In this paper, we propose a secure logging scheme for Forensic Computing. Forensic Computing is the process conducted to identify the method of an attack and intruders in the case of system compromise. In Forensic Computing, trustworthy logs admissible for court are needed. Moreover, since the log contains various confidential information, the confidentiality of the log must be preserved. Our scheme achieves the integrity of logs and fine-grained access control for logs with small overhead size using the signature tree and Forward Integrity.
