Abstract:
As more and more people are using smartphones these days, a great deal of important information, such as personal information and the important documents of corporations among other things, are being saved on smartphones. Unlike a PC, people can access another person’s smartphone without great difficulty, and there is a high possibility of losing one’s smartphone. If smartphone is lost without encryption, important information can be exploited. In addition, the open cryptographic library for PCs cannot be used due to the limited performance of the smartphone. This paper introduces the optimization implementation technique for the smartphone OS and the results of using that technique. In addition, the results of a speed comparison with the open cryptographic library will be presented. According to the results of comparing the one-time encryption implementation time with the open cryptographic library, the performance time was improved by 12% for Windows Mobile, 8.57% for iOS, and 39.62% for Android.
