Objectives: To increase needed for exchanging digital photos electronically, due to alarming demand for multimedia applications, and because of the increasing use of images in electronic processes. Hence, the need for protection by unauthorized user is necessary. Method: This paper primarily is focusing on the necessary protection of these images using a specific analyzes algorithm: Advanced Encryption Standard (AES) with a full its description, which is known as an algorithm (Rijndael). Findings: It will be determined the address decryption, which is made up of different styles in all encryption and decryption steps in order to protect the valuable information. This algorithm will be implemented on MATLAB software programming. Application: The above results and analysis for this crypto system based on AES algorithm give a high performance. So we have reason to believe that use this method to encrypt the image will have a very good prospect in the future.

Almost all cryptographic storage systems need re-encryption when revoking users. These systems differ from each other only in the timing of re-encryption. As re-encryption is an expensive operation, it is significant to avoid re-encryption. To avoid re-encryption in cryptographic storage systems, field programmable gate array (FPGA) and application-specific integrated circuit (ASIC) hardware module have been integrated into encrypt-on-disk object store system in this paper, letting private key never leave the hardware module and object key existing only in hardware module in plaintext. Anyone who does not know private or object key, so when revoking users, just needs to modify access control list (ACL) to delete the privileges of the users. To facilitate file sharing and key management, a group is adopted. In the system, almost all computationally expensive cryptographic operations are through FPGA/ASIC hardware module. Once a creator revokes some users, objects do not need re-encryption. How to use ACL and FPGA/ASIC hardware module to authenticate and authorise is also described. And the procedure of object store and the distribution of metadata are detailed. Finally, an encrypt-on-disk object store prototype system is implemented using FPGA in software solution with tested and effective performance.

Abstract. Almost all cryptographic file sharing systems need re-encryption when the sharing was revoked. These systems differ from each other only in the timing of re-encryption. As re-encryption is an expensive operation, it is significant to avoid re-encryption. The purpose of this paper is to advise a direction to avoid re-encryption and facilitate file sharing in cryptographic file sharing system. A Black-box model is set up to achieve this objective. In the model, FPGA or ASIC chips are used to act as the black-box as they have been extensively researched and applied in cryptography. Some applications of FPGA and ASIC in cryptography are detailed in this paper. Their feasibility to be functioned as the black-box is discussed. Also a software implementation on FPGA is attached with tested and effective performance.
