Abstract
With the rapid growth of the embedded system market, especially in the area of ubiquitous e-services, an increasmg number of embedded systems are required to deal with sensitive and private information. In this study, a new algorithm to secure and protect databases is proposed by using a Dynamic Rey (DR) and reverse string for each character in the string (or field in the file of a database) and each string (or record in the file of a database). In this paper, a new encryption algorithm for database protection based on Dynamic Rey and Reverse String (DKRS). The proposed algorithm (DKRS) specifically protecting the sensitive data because the (DKRS) is using dynamic key for each character in the string. The dynamic key is generated using special equation that depends on length of string, order of the character in the string, ASCII code of the character and string sequence. The (DKRS) algorithm guarantees that no duplicate encryption for each character and each record will be different. Also, (DKRS) algorithm ensures a different encryption for the duplicate data. The (DKRS) algorithm is using the reverse string before the encryption and many steps after that to add more complexity.
