Cryptography issues
Cryptography[1].ppt (Size: 352 KB / Downloads: 103) Confidentiality: only sender, intended receiver should “understand” message contents sender encrypts message receiver decrypts message End-Point Authentication: sender, receiver want to confirm identity of each other Message Integrity: sender, receiver want to ensure message not altered (in transit, or afterwards) without detection Polyalphabetic encryption n monoalphabetic cyphers, M1,M2,…,Mn Cycling pattern: e.g., n=4, M1,M3,M4,M3,M2; M1,M3,M4,M3,M2; For each new plaintext symbol, use subsequent monoalphabetic pattern in cyclic pattern dog: d from M1, o from M3, g from M4 Key: the n ciphers and the cyclic pattern Block ciphers Message to be encrypted is processed in blocks of k bits (e.g., 64-bit blocks). 1-to-1 mapping is used to map k-bit block of plaintext to k-bit block of ciphertext

Palladium Cryptography
Palladium Cryptography.docx (Size: 204.16 KB / Downloads: 22) ABSTRACT 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. Palladium is a content protection concept that has spawned from the belief that the pc, as it currently stands, is not architecturally equipped to protect a user forms the pitfalls and challenges that an all-pervasive network such as the Internet poses. As a drastic change in pc hardware is not feasible largely due to economic reasons, palladium hopes to introduce a minimal change in this front. A paradigm shift is awaited in this scenario with the advent of usage of palladium, thus making content protection a shared concern of both software and hardware. In the course of this paper the revolutionary aspects of palladium are discussed in detail. A case study to restructure the present data security system of JNTU examination system using palladium is put forward. INTRODUCTION Many organizations posses valuable information they guard closely. As more of this information is stored in computers the need of data security becomes increasingly important. Protecting this information against unauthorized usage is therefore a major concern for both operating systems and users alike. Palladium-"a revolutionary breakthrough in data security" Palladium is the code name for a revolutionary set of "features" for the "windows" operating system. The code name of this initiative -"palladium", is a moniker drawn from the Greek mythological goddess of wisdom and protector of civilized life. Till date most forms of data security have been software oriented with little or no hardware involvement. Palladium can be touted as the first technology to develop software-hardware synchronization for better data security. Hardware changes incorporated by palladium are reflected in the key components of the CPU, a motherboard chip (cryptographic co-processor), input and output components such as the graphics processor etc. When combined with a new breed of hardware and applications, these "features" will give individuals and groups of user's greater data security, personal privacy, and system integrity. In addition, palladium will offer enterprise consumers significant new benefits for network security and content protection. WORKING OF PALLADIUM Palladium is a new hardware and software architecture. This architecture will include a new security computing chip and design changes to a computer's central processing unit (CPU), chipsets, and peripheral devices, such as keyboards and printers. It also will enable applications and components of these applications to run in a protected memory space that is highly resistant to tempering and interference. The pc-specific secret coding within palladium makes stolen files useless on other machines as they are physically and cryptographically locked within the hardware of the machine. This means software attacks can't expose these secrets. Even if a sophisticated hardware attack were to get at them, these core system secrets would only be applicable to the data within a single computer and could not be used on other computes. PROTECTION USING PALLADIUM Palladium prevents identity theft and unauthorized access to personal data on the user's device while on the internet and on other networks. Transactions and processes are verifiable and reliable through the attestable hardware and software architecture and they cannot be imitated. With palladium, a system's secrets are locked in the computer and are only revealed on terms that the user has specified. In addition, the trusted user interface prevents snooping and impersonation. The user controls what is revealed and can separate categories of data on a single computer into distinct realms. Like a set of vaults, realms provide the assurance of separability. With distinct identifiers, policies and categories of data for each, realms allow a user to have a locked-down work environment and fully open surfing environment at the same time, on the same computer. CONCLUSION Today, it managers face tremendous challenges due to the inherent openness of end-user machines, and millions of people simply avoid some online transactions out of fear. However, with the usage of "palladium" systems, trustworthy, secure interactions will become possible. This technology will provide tougher security defenses and more abundant privacy benefits than ever before. With palladium, users will have unparalleled power over system integrity, personal privacy and data security. Thus it wouldn't be exaggeration to say that palladium is all to secure the computing world in ways unimaginable
