KEAMANAN WEB FOTO GALERY DENGAN MENGGUNAKAN udALGORITMA 3DES (TRIPLE DATA ENCRYPTION STANDARD)

摘要

Many users of social media often publish pictures or drawings to the internet to document of a moment or event. Most of the users who like to upload their images to the public, just know that they've uploaded images are stored in certain media means, where the images can be viewed at any time and in the download again if needed. But actually there are some things that are very risky if upload the image to the public media, images uploaded can be downloaded by others are used for specific purpose. Of course, an advantage also if you have another place to store the data. Then it is most at risk, usually images are stored in the form of an album that marks the location of the image storage position in public media in the way this source path url link. The storage location can be accessed for download all data or even deleted by certain parties. In this thesis, an examination of the implementation of the encryption system to secure the source path url link using 3DES algorithm. Tests carried out using firebug and the data showing the wireshark source path url link has been encrypted. The average time required for the encryption process is as much as ten times 0.001099992 milliseconds, it also depends on the length of the plaintext and the hardware used. So with the data that has been encrypted url can meet the objectives of cryptography, the source path url confidentiality can be maintained, the data url can not be read easily, and as well as the authenticity of the data is maintained from the URL
