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.
Tamper resistant screw Two pentalobe screws left and right of the lightning connector of an iPhone 6S Plus The pentalobe security screw [ 1 ] (Apple nomenclature), or pentalobe screw drive, is a five-pointed tamper-resistant system used by, but not limited to, Apple in their products. [ 1 ]
In police work, tamper-evident techniques must often be used to guard access to evidence, providing means of storing items and samples in a way which can be used to prove that they were not altered after their collection. Special tamper-evident evidence bags are available, to be used following a strict protocol. [6]
Each module contains one or more secure cryptoprocessor chips to prevent tampering and bus probing, or a combination of chips in a module that is protected by the tamper evident, tamper resistant, or tamper responsive packaging. A vast majority of existing HSMs are designed mainly to manage secret keys.
True tamper-proof — rather than merely tamper-resistant — screw drives include the breakaway head and one-way screw drives. Both tamper-proof and tamper-resistant drives are commonly used in vandalism- and attack-prone areas, such as public restrooms, prisons, [69] and banks; tamper-resistant in similar applications, and on ...
Standard Torx drivers can be used to drive Torx Plus screws, but not to full torque because of the loose fit. Torx Plus drivers will not fit into standard Torx screws. A tamper-resistant version of Torx Plus exists having five lobes rather than six, plus a solid post in the center, and is used for security as the drivers are uncommon. [20]
This plug has an elongated rectangular cross-section, inserts into a Type-A receptacle on a downstream port on a USB host or hub, and carries both power and data. Captive cables on USB devices such as keyboards or mice terminate with a Type-A plug. The Type-B plug: This plug has a near square cross-section with the top exterior corners beveled.
A tamper-resistant security module (TRSM) is a device that incorporates physical protections to prevent compromise of cryptographic security parameters that it contains. There are varying levels of protection afforded by TRSMs: Tamper-resistance: make intrusion difficult, usually by employing hardened casing
