WebThe RC4 stream cipher had a number of design flaws and weaknesses. WEP also used a small IV value, causing frequent IV reuse. Lastly, the way that the encryption keys were generated was insecure. What symmetric encryption algorithm does WPA2 use? AES. WPA2 uses CCMP. This utilizes AES in counter mode, which turns a block cipher into a stream ... WebEncryption Time of RC4 and AES b) Decryption time based on different packet size In Graph 2, we show the performance of cryptographic algorithms in terms of decryption time. Here, we compare the encryption time of AES and RC4 algorithm over different packet size. RC4 takes less time to decrypt files w.r.t. AES. parts of the eye drawing https://erinabeldds.com
