Analysis of encryption schemes in modern ransomware
Rad Hrvatske akademije znanosti i umjetnosti. Matematičke znanosti, 2021•hrcak.srce.hr
Sažetak In the past few years, activity of ransomware increased. As new variants and
families of ransomware are developed, security systems have to keep up. Well designed
encryption system is at the heart of ransomware and even a small mistake in the algorithm
can break it. This paper analyzes 10 ransomware samples from various families. The goal of
the analysis is to describe encryption schemes used in current ransomware. This includes
key generation and storage, symmetric and asymmetric ciphers and their chosen …
