“…MLS was developed by US Military in 1970 [10], that is considered one of the computer applications that protects data in Operating Systems, Networks and Databases by classifying data and users to different security levels. Many organizations utilize MLS security during its operation, such that SELinux [11], Oracle Label Security (OLS)[12], MLChat[13] and cloud security [14]. Actually, there are four levels of security: Top Secret (TS), Secret (S), Confidential (C), Unclassified (U).…”

Multilevel Security (MLS) is one of the ways that protects the stored information in the computer and mobile devices. It classifies users and information into levels of security; thus, the user can access information within its level or less.A smartphone is used in managing some of businesses, controlling the home and car devices within the smart city environment by using a set of data stored in the database. The database is used by more than one authorized user some of this data is confidential and important that requires protection from un authorized users.In this research a proposed system to implement the MLS principle within three levels of security is presented. The first level gives the user its own security level. The second level transfers users through the system parts according to their security level (system administrator or regular user). The third level allows users to manipulate the stored encrypted data in SQLite database by using a simple and quick cryptographic algorithm.The proposed system is implemented in the smart mobile devices which are supported by the Android operating system. The experimental result showed that the proposed system has the ability to protect the data in the database and prevents users to view the data at upper levels. Also, the inability of users to change the security level of data that prevents the leak of data from the upper security levels to the lower level. Moreover, the proposed system works quickly and needs a little storage space.

“…Chinnasamy et al [15] explained the weakness of traditional symmetric and asymmetric algorithm and proposed a new algorithm that is the combination of ECC and Blowfish, which provides the high security and confidentiality to the data. Tallapally and Manjula [16] proposed a multilevel security scheme that provide more security as compare to single level security in encryption. The proposed algorithm is faster and safe in multiple direction.…”

“…Just the approved individuals can unscramble the information since the will require the keys. In the encryption-unscrambling measure, the individual who scrambles the information must give the beneficiaries the capacity to translate the information either by providing the manual or passwords or by the utilization of computerized decoding programming [16]- [18] The advanced encryption standard (AES) is a symmetric square code picked by the U.S. government to secure grouped data. AES is executed in programming and equipment all through the world to scramble touchy information.…”

<p class="Abstract">In this tumultuous 21st century, we are surrounding by lots of applications such as social media websites all over the internet or this era can also define as digital era in which everything is accessible over the internet. There are billions of internet users all over the world and they share their information over the same and because of this lots of people intentionally trying to steal the confidential data of other people, so it is always advisable to share and store data in encrypted form. In this paper, we discuss different encryption and decryption algorithms and compare them with respect to time take by these algorithms for encrypting and decrypting different sizes of files.</p>
