And when applied in End-To-End Encryption security scenario, can enhance the encryption effectiveness, key organization and security thus, eliminating the gaps inherent in AES. Through the performance evaluation analysis of various cryptographic algorithms, it was concluded that the hybrid (AES-RSA) encryption algorithm is more secured. The following performance evaluation parameters such as encryption/decryption time, different key size, CPU utilization, memory consumption rate and overall process time, was utilized. To ascertain which would be better suited for End-To-End Encryption security in a network or system. In this research, we conducted a performance evaluation analysis on various cryptographic algorithms such as Advance Encryption Standard (AES), Blowfish, Data Encryption Standard (DES), Hybrid (AES-RSA) and Triple Data Encryption Standard (3DES). Yet, the understand of the security goals (confidentiality, integrity, authentication) remain vague to users, such as how the security goals offer protection, and if they value that protection. Several widespread communication tools (WhatsApp, Signal, Telegram, iMessage) have implemented end-to-end encryption, as a major selling point.
End-to-End (E2E) encryption in mobile communication applications delivers confidentiality between users, defending messages against snooping. Digital communications surveillance is a major security concern in the world at large.
