Cyber Crimes

Cyber Security, over the last few years, has been a topic of great research given the number of cyber crimes have been increasing. To provide cyber security , constant efforts are being made to secure the communications and to protect user data using various cryptography techniques. With the increasing number of cryptography, the number of keys used to secure communications also sees a high. It is always difficult to manage these keys and their identity in a multi process communication environment. This paper brings into light an approach for the enhancement of data security and cryptographic key management using a policy based key management system. An on the device approach is proposed which uses the file system to create a secure storage with enhanced security for the storage of the data . The access to this storage is governed by policies to allow an application based access to the storage. This model will provide a highly scalable secure storage and management of keys.

Cryptographic Key

Cryptographic technologies that have become widespread in the world are inex- tricably linked to the issues of secure storage, use of keys, and key exchange. Often, insecure key management reduces the quality of even exceptionally good systems, since the security of the algorithm is concentrated mainly in the key. This paper proposes a key management model in cryptographic systems. The model is based on creating a unified key database for all users. This database is filled with keys of a certain length, which are generated using a pseudo-random sequence generation algorithm.

Abstract-- With increase in complexity of data, security, it is difficult for the individuals to prevent the offence. Thus, by using any automation or software it’s not possible by only using huge fixed algorithms to overcome this. Thus, we need to look for something which is robust and feasible enough. Hence AI plays an epitome role to defense such violations. In this paper we basically look how human reasoning along with AI can be applied to uplift cyber security.

Background: Cloud storage is generally used to provide on-demand services with sufficient scalability in an efficient network environment, and various encryption algorithms are typically applied to protect the data in the cloud. However, it is non-trivial to obtain the original data after encryption and efficient methods are needed to access the original data. Methods: In this paper, we propose a new user-controlled and efficient encrypted data sharing model in cloud storage. It preprocesses user data to ensure the confidentiality and integrity based on triple encryption scheme of CP-ABE ciphertext access control mechanism and integrity verification. Moreover, it adopts secondary screening program to achieve efficient ciphertext retrieval by using distributed Lucene technology and fine-grained decision tree. In this way, when a trustworthy third party is introduced, the security and reliability of data sharing can be guaranteed. To provide data security and efficient retrieval, we also combine active user with active system. Results: Experimental results show that the proposed model can ensure data security in cloud storage services platform as well as enhance the operational performance of data sharing. Conclusion: The proposed security sharing mechanism works well in an actual cloud storage environment.

Cloud computing cyber security is a subject that has been in top flight for a long period and even in near future. However, cloud computing permit to stock up a huge number of data in the cloud stockage, and allow the user to pay per utilization from anywhere via any terminal equipment. Among the major issues related to Cloud Computing security, we can mention data security, denial of service attacks, confidentiality, availability, and data integrity. This paper is dedicated to a taxonomic classification study of cloud computing cyber-security. With the main objective to identify the main challenges and issues in this field, the different approaches and solutions proposed to address them and the open problems that need to be addressed.
