  2. Tamperproofing - Wikipedia

    en.wikipedia.org/wiki/Tamperproofing

    Tamperproofing 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.

  3. Tamper-evident technology - Wikipedia

    en.wikipedia.org/wiki/Tamper-evident_technology

    Identify all feasible methods of unauthorized access into a product, package, or system. In addition to the primary means of entry, also consider secondary or "back door" methods. Control or limit access to products or systems of interest. Improve the tamper resistance by making tampering more difficult, time-consuming, etc.

  4. Anti-tamper software - Wikipedia

    en.wikipedia.org/wiki/Anti-Tamper_Software

    There are no provably secure software anti-tampering methods; thus, the field is an arms race between attackers and software anti-tampering technologies. [2] Tampering can be malicious, to gain control over some aspect of the software with an unauthorized modification that alters the computer program code and behaviour.

  5. Hardware backdoor - Wikipedia

    en.wikipedia.org/wiki/Hardware_backdoor

    A hardware backdoor is a backdoor implemented within the physical components of a computer system, also known as its hardware. They can be created by introducing malicious code to a component's firmware , or even during the manufacturing process of a integrated circuit , known as a hardware trojan .

  6. Hardware security - Wikipedia

    en.wikipedia.org/wiki/Hardware_security

    Hardware backdoors are backdoors in hardware. Conceptionally related, a hardware Trojan (HT) is a malicious modification of electronic system, particularly in the context of integrated circuit. [1] [3] A physical unclonable function (PUF) [6] [7] is a physical entity that is embodied in a physical structure and is easy to evaluate but hard to ...

  7. Hardware Trojan - Wikipedia

    en.wikipedia.org/wiki/Hardware_Trojan

    A Hardware Trojan (HT) is a malicious modification of the circuitry of an integrated circuit. A hardware Trojan is completely characterized by its physical representation and its behavior. The payload of an HT is the entire activity that the Trojan executes when it is triggered.

  8. Cannibalization (parts) - Wikipedia

    en.wikipedia.org/wiki/Cannibalization_(parts)

    Cannibalization of machine parts, in the maintenance of mechanical or electronic systems with interchangeable parts, refers to the practice of removing parts or subsystems necessary for repair from another similar device, rather than from inventory, usually when resources become limited. The source system is usually crippled as a result ...

  9. Error-tolerant design - Wikipedia

    en.wikipedia.org/wiki/Error-tolerant_design

    It is the human equivalent of fault tolerant design that allows equipment to continue functioning in the presence of hardware faults, such as a "limp-in" mode for an automobile electronics unit that would be employed if something like the oxygen sensor failed.
