Abstract

In this paper, a key-backup technique for the recovery of files that have been encrypted by ransomware is proposed. Ransomware interferes with the victim’s system through the enactment of abnormal behavior, which is the locking of the victim’s system or the encryption of the system or files. Ransomware writers require money from victims as a condition for the recovery of the encrypted files and systems that have been seized; accordingly, systems that are infected by ransomware cannot be repaired without a decryption key, making the employment of detection and recovery methods urgent. In this paper, a prevention technique for the backing up of encryption keys in a secure repository, and that can enable the recovery of ransomware-infected systems and ransomware-encrypted files. The proposed technique can be used to repair systems that have been infected by ransomware, thereby ensuring safety regarding such malicious codes.
