“…The tool was executed for more than 48 hours on ASUS X53S Laptop powered with Intel Core i5 2430 M processor with a clock speed of 2.40 GHz (Turbo-Boost to 3.1 GHz)28 [32], but it was unable to break 1 round of Feistel function of CSL algorithm. Therefore, our CSL algorithm avoids a brute force attack for a rational period [9].…”

“…Since individual audits of these can task can be repetitive and inefficient, the TPA would naturally be able to efficiently conduct multiple auditing tasks at the same time. To address these problems, our work utilizes the technique of symmetric key encryption scheme CSL algorithm along with ultra-lightweight and fastest hashing function BLAKE3, It allows TPA to carry out the auditing without required local data copy and thus reduces coordination and overhead compared with direct approaches to data auditing [8,9]. By integrating the compressed data using LZ4 compression scheme and hashing function with a nonce, makes our proposed system works at high speed further ensuring The TPA did not know about the data content stored on the cloud server during the efficient auditing process.…”

Over the last decade, many enterprises around the world migrating from traditional infrastructure to cloud resources in order to cut down operational and capital expenditure. With cloud computing, huge amount of data transactions is communicated between cloud consumers and cloud service providers. However, this cloud computing enables surplus security challenges associated to unauthorized access and data breaches. We proposed in this paper a trusted third-party auditor (TPA) model which uses lightweight cryptographic system and lightweight hashing technique to ensure data security and data integrity to audit the cloud users outsourced data from cloud service providers. With our proposed system, we solve the concern of data reliability using data correctness and verification analysis and error recovery analysis. The time complexity of our proposed system is less as compared with other TPA model. Our proposed system also shows resistance against various known cryptanalytic attacks, the performance and extensive compression technique of our proposed system are probably secure and highly proficient.
