The result of the hybrid encryption process has an additional security level with overall improved system performance. Symmetric and asymmetric cryptography algorithms have their own advantages and disadvantages. In general, symmetric ciphers are considerably faster than asymmetric

WebNov 23, 2024 · Symmetric encryption algorithms use the same encryption key for both encryption and decryption. (Unlike asymmetric encryption algorithms, which use two different keys.) Encryption algorithms, in general, are based in mathematics and can range from very simple to very complex processes depending on their design. WebThis is achieved by utilizing a set of sound existing symmetric encryption algorithms, namely, the Advanced Encryption Standard,MARS,RC6, Serpent and Twofish. The identity of the algorithm used to secure the current message, along with other cryptographic parameters (e.g. mode of operation, key length), are hidden from anyone except the …
