WebTo a great extent, the efficiency of blockchain depends on the encryption algorithm [41]. Thus, in the proposed framework, we compared the two well-known encryption … WebBecause each of these has a different level of cryptographic complexity, it is usual to have different key sizes for the same level of security, depending upon the algorithm used. For example, the security available with a 1024-bit key using asymmetric RSA is considered approximately equal in security to an 80-bit key in a symmetric algorithm. [1] WebNov 14, 2024 · RSA is more computationally intensive than AES, and much slower. It’s normally used to encrypt only small amounts of data. How AES and RSA work together A major issue with AES is that, as a symmetric algorithm, it requires that both the encryptor and the decryptor use the same key. th-30013
