Abstract: The growing world of digitisation has given rise to cybercrimes. Digital forensics is the process of collecting lawful evidence. Such evidence plays a very crucial role in the court of law to demonstrate the fact explicitly against the crime of the suspect. To ensure the admissibility of evidence in the court of law during trials, it is important to maintain evidence using a proper evidence management system. We propose the use of a unidirectional multi-hop proxy re-encryption scheme for authority delegation. This proposed system will help in securely delegating access to digital evidence. The re-encryption scheme perceives a clearer perception of security and validates the usefulness of proxy re-encryption as a method of adding access control to a secure evidence management system. The correctness analysis of the proposed scheme is validated by using BAN logic. The security analysis using the AVISPA tool shows that the proposed scheme is safe against various security attacks.

Keywords: digital forensics; evidence management; proxy re-encryption; cybercrime; BAN logic; AVISPA.
