Transparent Encryption Technique for Trusted Computing

Abstract

Abstract Trusted computing is a technology that has been developed to make a computer safer and more trustworthy. The main purpose of trusted computing is to ensure that only authorized user will be able to use and access information stored inside the computer. Although the current trusted computing technology is capable of providing the level of trustworthiness required, it is still subjected to physical attack. In order to solve this problem, the TPM-UAM model has been proposed. However, in order to provide better protection, it is important that data inside the computer to be encrypted whenever it is not used and decrypted whenever it needs to be used. A number of encryption techniques are available such as RSA, AES, DES/3DES, Twofish, Blowfish, IDEA, SEAL, RC4. However, time taken for encrypting and decrypting data by using these techniques is huge. This paper describes a research work that is currently undertaken in order to develop a new encryption mechanism that can provide very fast and transparent encryption and decryption services for trusted computers.
