【 摘 要 】

The organization maintains various information in cloud which is a loosely coupled environment. However, the nature of cloud encourages the threats in different level. Among them the data security has been a keen issue being identified and challenges the service provider. To improve the data security performance, different algorithms have been discussed, but suffer to achieve higher performance in data security. To design more secured data security algorithm, a light weight proactive padding based crypto security system (LPP-CS) is presented in this paper. The method generates keys to support the crypto systems based on the prime values. The keys are generated from the set of prime numbers which have been used to pad the cipher text generated. The end user will be given with the key which is generated and distributed at the assignment. The encryption is performed in block level and for each block of data different keys has been used which challenges the adversary highly. The selection of prime factors and keys are suitable for any specific time window and has been iterated frequently. The proposed LPP-CS algorithm improves the performance of cloud data security with less time complexity.
