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 ]
An HSM in PCIe format. A hardware security module (HSM) is a physical computing device that safeguards and manages secrets (most importantly digital keys), and performs encryption and decryption functions for digital signatures, strong authentication and other cryptographic functions. [1]
Tamper-resistant automotive ignition switches discourage car theft. Vandal-resistant switches are often low-voltage, low current, so-called "signal" types intended to trigger a change in state, perhaps from "off" to "on" and vice versa. The mechanical types often have gold-plated contacts that do not corrode, to allow reliable low-power ...
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]
The Apple Computer Mac OS X operating system has provided software for disc data encryption since Mac OS X Panther was issued in 2003 (see also: Disk Utility). [citation needed] Additional software can be installed on an external USB drive to prevent access to files in case the drive becomes lost or stolen.
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
