Ch. Upendar Rao, M.Deva Sandeep, K.Harsha Vardhan, Dasi Joseph, V.Bhavya Laxmi 06 04 One of the main concerns in cloudcomputing is how to effectively manage accesscontrols for data using cryptography Whilechallenging cryptographic methods are an appealingsolution that both individuals and businesses want toadopt To address this issue a potential solutioncalled CryptSecure has been proposed in this studyThe primary goal of CryptSecure is to enabledynamic access control through cryptography Torevoke access permissions the encrypted data in thecloud is modified as directed by CryptSecure Thistechnique involves a symmetric code systemconsisting of file codes and revocation codes Whena revocation occurs and an authorized entity uploadsa new revocation code to the cloud the file isencrypted with an additional layer of security Thistriggers a corresponding adjustment in the encryptedcode systemTo reduce encryption layers and keys CryptSecureuses three key techniques that address scalabilityconcerns This enables efficient dynamic accesscontrol without needing resourceintensive datatransmission or decryption Authorization to accesscan also be withdrawn quickly The formalimplementation of the system demonstratesCryptSecures security and effectiveness in enablingefficient and secure dynamic access control forcloudhosted data This approach has proveninvaluable for individuals and organizations to ensureremote data is accessible smoothly and securely Copyright (c) World Journal of Pharmaceutical Seiences.
