Trusted Computing
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 that is distinct from the field of Confidential Computing. The core idea of trusted computing is to give hardware manufacturers control over what software does and does not run on a system by refusing to run unsigned software. With Trusted Computing, the computer will consistently behave in expected ways, and those behaviors will be enforced by computer hardware and software. Enforcing this behavior is achieved by loading the hardware with a unique encryption key that is inaccessible to the rest of the system and the owner. TC is controversial as the hardware is not only secured for its owner, but also secured ''against its owner''. Such controversy has led opponents of trusted computing, such as free software activist Richard Stallman, to refer to it instead as ''treacherous computing'', even to the point wh ...

Trusted Computing Group
The Trusted Computing Group is a group formed in 2003 as the successor to the Trusted Computing Platform Alliance which was previously formed in 1999 to implement Trusted Computing concepts across personal computers. Members include Intel, AMD, IBM, Microsoft, and Cisco. The core idea of trusted computing is to give hardware manufacturers control over what software does and does not run on a system by refusing to run unsigned software. History On October 11, 1999, the Trusted Computing Platform Alliance (abbreviated as TCPA), a consortium of various technology companies including Compaq, Hewlett-Packard, IBM, Intel, and Microsoft, was formed in an effort to promote trust and security in the personal computing platform. In November 1999, the TCPA announced that over 70 leading hardware and software companies joined the alliance in the first month. On January 30, 2001, version 1.0 of the Trusted Computing Platform Specifications was released IBM was the first original equipment m ...

Dell
Dell is an American based technology company. It develops, sells, repairs, and supports computers and related products and services. Dell is owned by its parent company, Dell Technologies. Dell sells personal computers (PCs), servers, data storage devices, network switches, software, computer peripherals, HDTVs, cameras, printers, and electronics built by other manufacturers. The company is known for how it manages its supply chain and electronic commerce. This includes Dell selling directly to customers and delivering PCs that the customer wants. Dell was a pure hardware vendor until 2009 when it acquired Perot Systems. Dell then entered the market for IT services. The company has expanded storage and networking systems. It is now expanding from offering computers only to delivering a range of technology for enterprise customers. Dell is a publicly-traded company (), as well as a component of the NASDAQ-100 and S&P 500. It is the 3rd largest personal computer vendor as ...

Memory Protection
Memory protection is a way to control memory access rights on a computer, and is a part of most modern instruction set architectures and operating systems. The main purpose of memory protection is to prevent a process from accessing memory that has not been allocated to it. This prevents a bug or malware within a process from affecting other processes, or the operating system itself. Protection may encompass all accesses to a specified area of memory, write accesses, or attempts to execute the contents of the area. An attempt to access unauthorized memory results in a hardware fault, e.g., a segmentation fault, storage violation exception, generally causing abnormal termination of the offending process. Memory protection for computer security includes additional techniques such as address space layout randomization and executable space protection. Methods Segmentation Segmentation refers to dividing a computer's memory into segments. A reference to a memory location incl ...

Tamper Resistance
Tamperproofing, conceptually, is a methodology used to hinder, deter or detect unauthorised access to a device or circumvention of a security system. Since any device or system can be foiled by a person with sufficient knowledge, equipment, and time, the term "tamperproof" is a misnomer unless some limitations on the tampering party's resources is explicit or assumed. ''Tamper resistance'' is resistance to tampering (intentional malfunction or sabotage) by either the normal users of a product, package, or system or others with physical access to it. Tamper resistance ranges from simple features like screws with special drives, more complex devices that render themselves inoperable or encrypt all data transmissions between individual chips, or use of materials needing special tools and knowledge. Tamper-resistant devices or features are common on packages to deter package or product tampering. Anti-tamper devices have one or more components: tamper resistance, tamper detecti ...

Direct Anonymous Attestation
Direct Anonymous Attestation (DAA) is a cryptographic primitive which enables remote authentication of a trusted computer whilst preserving privacy of the platform's user. The protocol has been adopted by the Trusted Computing Group (TCG) in the latest version of its Trusted Platform Module (TPM) specification to address privacy concerns (see also Loss of Internet anonymity). ISO/IEC 20008 specifies DAA, as well, and Intel's Enhanced Privacy ID (EPID) 2.0 implementation for microprocessors is available for licensing RAND-Z along with an open source SDK. Historical perspective In principle the privacy issue could be resolved using any standard signature scheme (or public key encryption) and a single key pair. Manufacturers would embed the private key into every TPM produced and the public key would be published as a certificate. Signatures produced by the TPM must have originated from the private key, by the nature of the technology, and since all TPMs use the same private key ...

RSA (algorithm)
RSA (Rivest–Shamir–Adleman) is a public-key cryptosystem that is widely used for secure data transmission. It is also one of the oldest. The acronym "RSA" comes from the surnames of Ron Rivest, Adi Shamir and Leonard Adleman, who publicly described the algorithm in 1977. An equivalent system was developed secretly in 1973 at Government Communications Headquarters (GCHQ) (the British signals intelligence agency) by the English mathematician Clifford Cocks. That system was declassified in 1997. In a public-key cryptosystem, the encryption key is public and distinct from the decryption key, which is kept secret (private). An RSA user creates and publishes a public key based on two large prime numbers, along with an auxiliary value. The prime numbers are kept secret. Messages can be encrypted by anyone, via the public key, but can only be decoded by someone who knows the prime numbers. The security of RSA relies on the practical difficulty of factoring the product of two ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
