From time immemorial, various encryptions have been used to protect data when sent to other people and stored in internal and external memory. In addition to traditional cryptography, recently, new cryptography such as quantum cryptography and DNA cryptography has been discussed. The main advantage of DNA cryptography is that it uses molecular complexity along with computational complexity to increase data security. This thesis intends to present a DNA-based cryptography method to increase security and prevent information disclosure, especially for secure data outsourcing. For this purpose, in the proposed method, mRNA and tRNA strands, as well as local binary pattern, will be used. After presenting this solution, its efficiency will be eva‎luated in terms of time, and the resistance against statistical attacks and information disclosure will be compared with other solutions. Also, the possibility of interval search on outsourced data without the need to decrypt them will be examined. On the other hand, considering that organizations have considered outsourcing due to the growing volume of information and the lack of computational resources and adequate storage, the proposed methodʹs performance will be examined in data outsourcing. The results show that the proposed DNA-based cryptography method can be used as a reliable and efficient solution.
