PERFORMANCE EVALUATION OF CIPHERING ALGORITHM FOR PDF ENCRYPTION
Abstract
improve security, but often require more computing power. The hybrid encryption approach
combines both symmetric and asymmetric encryption elements to compensate for performance
and security.Due to growing concerns about cybersecurity, businesses, governments, and
individuals need to choose the most appropriate encryption technology to protect sensitive
documents. The purpose of this study is to evaluate the performance of various degradation
algorithms of PDF encryption and compare the advantages and disadvantages in terms of
encryption speed, decryption duration, security, and computational efficiency. This result will help
you choose the most effective encryption method to protect your PDF files and contribute to
improving digital security.
1.2 MOTIVATION OF THE STUDY
The motivation behind the study is due to increased cyber threats, data injuries and increased
unauthorized access to sensitive information by increasing the need for secure digital document
management. Businesses, government agencies and individuals rely heavily on portable document
format (PDF) files to store and exchange important data, making sure security is a top priority
(Singh and kaur, 2018 ).
1.2.1 Key motivation:
a. Rising cybersecurity threats
i. Cyberattacks such as hacking, phishing, ransomware, and non-exempt access have made
digital documents an urgent i
