Enhanced Public Key Security Using Cuckoo Search Optimization and Improved AES Algorithm

The challenging element is keeping our data secure in the open. Six out of ten people in the digital era use smart devices and save their data in an unencrypted format. It is our responsibility to preserve publicly available data. Cryptography refers to the process of encrypting and decrypting personal information. In this work, we provide a cuckoo search algorithm-based public key security technique. Both encryption and decoding require keys. When given a list of keys, the user must select the strongest one; in this case, cuckoo search is used to determine the best key. Once identified, the key will be used for both encryption and decryption. The greatest and perfect key is discovered utilizing a key breaking approach. The optimal key is one that takes the longest to break. The Cuckoo Search Method is used to find the best key. This is how we can safeguard our public-domain data. Additional modifications in data sizes are used to identify the best output of this process.
