3. I NTRODUCTION : As we tend towards a more and more computer centric world, the concept of data security has attained a paramount importance. Though present day security systems offer a good level of protection, they are incapable of providing a trust worthy environment and are vulnerable to unexpected attacks.

4. T RUSTED C OMPUTING : Trusted Computing (TC) is a technology developed and promoted by the Trusted Computing Group. The term is taken from the field of trusted systems and has a specialized meaning. With Trusted Computing, the computer will consistently behave in expected ways, and those behaviours will be enforced by hardware and software. In practice, Trusted Computing uses cryptography to help enforce a selected behaviour.

5. H ISTORY OF P ALLADIUM : The code name of the initiative is "Palladium," is Drawn from the Greek mythological goddess of wisdom and Protector of civilized life. With "Palladium," Microsoft aims to Foster a significant evolution in personal and business Computing through the development of a new set of features That will be included in a future version of the Microsoft Windows operating system.

6. W HAT IS P ALLADIUM C RYPTOGRAPHY ? "Palladium" is Microsoft code name for an evolutionary set of features for the Windows operating system. Combined with a new breed of hardware and applications, these features will give individuals and groups of users greater data security, personal privacy, and system integrity. Palladium is not a separate operating system. It is based in architectural enhancements to the windows kernel and to computer hardware, including the CPU, peripherals and chipsets, to create a new trusted execution subsystem.

7. C ONTINUE … "Palladium" will greatly reduce the risk of many viruses and spyware software that captures and reports information from inside your PC -- and other attacks.

8. C OMPONENTS OF PALLADIUM: Hardware components 1. Trusted space 2. Sealed storage 3. Secure input and output Software components 1. Nexus (a technology formerly referred to as the trusted operating root ) 2. Trusted agents

9. H ARDWARE COMPONENTS Trusted space : This is an execution space is protected from external software attacks such as a virus. Sealed storage : Sealed storage is an authenticated mechanism that allows a program to store secrets that cannot be retrieved by non-trusted programs such as a virus or Trojan horse. Secure input and output : A secure path from the keyboard and mouse to palladium applications and a secure path from palladium applications to the screen ensure input- output security.

10. S OFTWARE COMPONENTS Nexus (a technology formerly referred to as the trusted operating root ) : This component manages trust functionality for palladium user-mode processes (agents). The nexus executes in kernel mode in the trusted space Trusted agents : A trusted agent is a program, a part of a program, or a service that runs in user mode in the trusted space. A trusted agent calls the nexus for security related services and critical general services such as memory management.

11. H OW IT WORKS : "Palladium" is a new hardware and software architecture. This architecture will include a new security computing chip and design changes to a computers central processing unit (CPU), chipsets, and peripheral devices, such as keyboards and printers.
