Hardware Cryptographic Coprocessor The Problem The Goal Example 1 – Database Example 2 Trusted Boot
Echeverri, Isabel, Fashion Editor has reference to this Academic Journal, PHwiki organized this Journal Hardware Cryptographic Coprocessor Peter R. Wihl Security in Software The Problem Need as long as secure computing in an environment where computing is distributed, insecure, in addition to even hostile More in addition to more, we use computers that belong to others, but we need to know our data is safe. The Goal Create a trusted computing device that can be added to an untrusted computing system to make it secure. Isolate your secure processing from the rest of your system.

Example 1 – Database Create a central database system that allows only authorized users to access to only their data on the system. Exclude even the system administrator from viewing any data in the database. Example 2 Trusted Boot You have an untrusted computing system, but you want to ensure that it boots the correct machine code. Want to make sure that the boot code has not been altered or tampered with Example 3 Protected Data At Rest (My Favorite!) You have sensitive data that you can access in a controlled, protected environment but must be protected when not being accessed Protection of data needed between use of it i.e. during transportation
A Secure Coprocessor A general-purpose computing environment Withst in addition to s physical attacks in addition to logical attacks Must run the programs that it is supposed to, in addition to must distinguish between the real device in addition to application in addition to a clever impersonator Must remain secure even if adversaries carry out destructive analysis of one or more devices Started in the early 1990s Evaluation Parameters Physical Protection (tamper resistant) Reliability (physical or electrical damage) Computational Ability (Speed bps) Communications Portability Cost Applications Generalized Access Generalized Revelation Autonomous Auditing Trusted Execution
Classes of Solutions IC Chip Cards (Smart Cards, Your GSM Phone has one) PCMCIA Tokens (Fortezza) Other Card Tokens (Secure ID) Smart Disks (Obsolete) Bus Cards (IBM 4758) Your Body (the future is now) FORTEZZA CRYPTOCARD Fortezza Features Data Privacy User ID Authentication Data Integrity Non-Repudiation Time stamping
RSA SecurID Software tokens support qualified smart cards or USB authenticators Stores symmetric key in addition to is PIN protected Stores digital credentials Only secures the login process The IBM 4758 Tamper-responding hardware design certified under FIPS PUB 140-1. Suitable as long as high-security processing in addition to cryptographic operations Hardware to per as long as m DES, r in addition to om number generation, in addition to modular math functions as long as RSA in addition to similar public-key cryptographic algorithms Secure code loading that enables updating of the functionality while installed in application systems IBM Common Cryptographic Architecture (CCA) in addition to PKCS 11 as well as custom software options Provides a secure plat as long as m on which developers can build secure applications The 4758 Architecture
SafeNet SafeXcel 241-PCI Card Provides industry-leading cryptography throughput as long as operations such as: DES in addition to Triple-DES encryption MD5 in addition to SHA-1 Hashing R in addition to om number generation Public key computations: – Diffie-Hellman key negotiation – RSA encryption in addition to signatures – DSA signatures SafeXcel 241-PCI Architecture
