A persistent and serious danger to the Internet is a denial of service attack on a large scale (DDoS) attack using machine learning. Because they originate at the low layers, new Infections that use genuine hypertext transfer protocol requests to overload target resources are more untraceable than application layer-based cyberattacks. Using network flow traces to construct an access matrix, this research presents a method for detecting distributed denial of service attack machine learning assaults. Independent component analysis decreases the number of attributes utilized in detection because it is multidimensional. Independent component analysis can be used to translate features into high dimensions and then locate feature subsets. Furthermore, during the training and testing phase of the updated source support vector machine for classification, their performance it is possible to keep track of the detection rate and false alarms. Modified source support vector machine is popular for pattern classification because it produces good results when compared to other approaches, and it outperforms other methods in testing even when given less information about the dataset. To increase classification rate, modified source support Vector machine is used, which is optimized using BAT and the modified Cuckoo Search method. When compared to standard classifiers, the acquired findings indicate better performance.

Data sharing is a significant functionality in cloud storage. These cloud storage provider are answerable for keeping the data obtainable and available in addition to the physical environment protected and running. Here we can securely, efficiently, and flexibly share data with others in cloud storage. A new public-key cryptosystems is planned which create constant-size cipher texts such that efficient allocation of decryption rights for any set of cipher texts are achievable. The uniqueness means that one can aggregate any set of secret keys and make them as packed in as a single key, but encircling the power of all the keys being aggregated. This packed in aggregate key can be easily sent to others or be stored in a smart card with very restricted secure storage. In KAC, users encrypt a file with single key, that means every file have each file, also there will be aggregate keys for two or more files, which formed by using the tree structure. Through this, the user can share more files with a single key at a time.
