CRYPTOGRAFHY FOR IMPROVING THE SECURITY OF CLOUD COMPUTING
The purpose of this article is to study and analyze the security threats in cloud environment and the applicability of cryptographic systems to protect the access to information resources. The threats to information security and the corresponding means for protection in cloud environment are discussed. Based on research and analysis of asymmetric and symmetric encryption are proposed flowcharts for secure communication over the Internet when using cloud services. The speed of different encryption and decryption of algorithms in cloud environment is measured, and are given recommendations for improving security.
