A block cipher divides the data into blocks … WebMar 16, 2024 · For the message encryption itself a symmetric cipher is used and for the key, the asymmetric one. Therefore, the slower, asymmetric method is used only for the key. So, faster symmetric data encrypts and decrypts the data. Thus, the whole process is more efficient especially for large amounts of data. 4.1.
