Activities correspondence is often used by agencies or companies, so that institutions or companies set up a special division to handle issues related to the letter management. Most of the distribution of letters using electronic media, then the letter should be kept confidential in order to avoid things that are not desirable. Techniques that can be done to meet the security aspect is by using cryptography or by giving a digital signature. The addition of asymmetric and symmetric algorithms, i.e. rsa and aesalgorithms, on the digital signature had been done in this study to maintain data security. The rsa algorithm was used during the process of giving digital signature, while the aes algorithm was used during the process of encoding a message that will be sent to the receiver. Based on the research can be concluded that the additions of aes and rsa algorithms on the digital signature meet four objectives of cryptography: Secrecy, Data Integrity, Authentication and Non-repudiation.

In this paper, we proposed a hybrid encryption algorithm in order to solve the security problems on lightweight data on the cloud storage service. This paper first improves the rsa algorithm in the cloud environment by increasing the length of the rsa key to an extent that it can quickly generate big primes. Then, we merge aes and rsa algorithms on the basis of the improved rsa algorithm. This is called a hybrid encryption algorithm which is suitable for security of the lightweight data in cloud storage environment in order to further enhance the confidentiality of data in the cloud. The experimental result shows that the hybrid encryption algorithm has advantages of fast encryption and decryption, more secure, and it is also able to settle the security problems of users' lightweight data in a certain extent.
