Download file to see previous pages As stated by Brain Gladman “it is fairly easy to create an encryption methodology that is safe, if it is functioning as intended and is correctly utilized. But it remains very hard to develop a methodology which does not compromise its security in circumstances whereby it is either abused or one or several of its subcomponents malfunction” (Gladman 2001, p. 4).
Physical tamper resistance is a characteristic or security concept that is applicable to various fields and not limited to the digital area or computing. Anti-tamper device comprises of tamper detection, tamper responses, and tamper resistance (Rannenberg et al. 2010, p. 16).
Various Physical tamper-resistant devices exist. These include high-end, low-end, and mid-range devices. However, one aspect worth noting is that these devices vary in cost and range classification in various countries. For example, China can cost and categorize a tamper resistance device according to geographical boundaries. Below is the list:
Just like the 4785 IBM, these resistant devices are of a very strong crypto system that is surrounded with a tamper sensing mesh. If an attempt at tampering is noticed, the mesh permanently deletes the main material and renders the device unrecoverable as well as unreadable. This device is significant for two reasons. Firstly, it is the only available commercial processor to have been successfully evaluated at the highest stages of tamper resistance. Secondly, the IBM 4758 has an extensive literature concerning its history, design evolution, protective procedures (Gladman 2001, p.3).
These kind of resistant devices comprise of a symmetric cryptosystem key. These devices are normally protected against unauthorized reads, and the procedures are designed on a very basic foundation. Cheap Microcontrollers are one of the examples of low-end resistant devices. ...Download file to see next pagesRead More

Handling devices

...?Handling devices Roller conveyor: One of the materials handling devices found in my organization belongs to the category of transport, i.e. roller conveyor. It is used to shift goods from one place to another. The material may be moved from one workplace to another or from a dock to another. The benefit of using the roller conveyor is that no matter how heavy the load may be, it gets moved with minimal inconvenience and time as it has to be moved mechanically by rollers. No manual work is involved in it. The smallest thing to be transported has to be broad enough to cover the width of at least three rollers in order to be moved (MHE Taxonomy, 1999). I would like to reduce the diameter of the rollers so...

Physical Tamper-Resistant Devices

...?Week 5 Hand-in Assignment By Physical Tamper-Resistant Devices One of the basic goals behind the development of a secure and safe computer or information system is to make sure that a number of cryptographic keys can only be accessed and utilized by their intended users and simply for their proposed tasks. In this scenario, encryption keys are stored in a computer that can be vulnerable to abuse, use, or alter by an illegal user or an attacker. For various reasons one of the most important techniques to secure encryption keys is to store them in a more protected tamper resistant hardware system. These systems can be utilized for a wide variety of applications varying from protected online cash transfer to e-mail and credit card... ...

Methicillin-resistant Staphylococcus aureus

...?In the workplace, the chronic illness renal disease patients need to go to the hospital and clinic frequently; therefore, the decontamination of theenvironment to prevent cross transmission is most beneficial. Moreover, nowadays, one of the most difficult to treat is Methicillin- resistant Staphylococcus aureus (MRSA). Decontamination ensures that there are no medical or health implications in the treatment process with regard to renal medicine. This is due to the possibility of infections that could hinder or act as counteractive measures towards the entire of treating renal diseases. Moreover, cleaning and decontamination alleviates all forms of erroneous diagnosis and reinfections with unknown pathogens, as well as conditions... or the...

Cloning Devices

...? By Eddy Gleitman Prof. Naeem Musa ISSC 361 November 23, Cloning Technology There is one thing common between droids, sheep and computers and that is, they can all be cloned. However, among all of these only the computer clones are believed to be most effective. In fact, the computer cloning can be further broken into software program cloning or hardware device cloning and the basic purpose of these techniques is to make a similar copy or duplicate of a current technology or device. It is an admitted fact that a cloned product is developed by a third-party organization instead of the firm that formerly created it. In this scenario, IBM compatible computers can be considered as an excellent example of...

Antibiotics resistant superbugs

...ANTIBIOTIC RESISTANCE SUPERBUGS Antibiotic Resistance Superbugs Continued use of antibiotics results to resistance thereby making it impossible for antibiotics to have the required effects on bacteria. In some instances, bacteria may form great resistances such that there is a wide range of antibiotics that cannot have influence on them. This makes it extremely hard to get rid of such bacteria and they are commonly referred to as superbugs. Some of the commonly encountered superbugs include methicillin-resistant Staphylococcus aureus (MRSA) and extended spectrum beta-lactamase (ESBL) among others. Antibiotic resistance problem has affected many parts of the world and resulted in many death cases each year. For example... , there are...

Antibiotic Resistant Bactria

...RESISTANCE TO ANTIBIOTICS Antibiotic resistance, according to Chadwick, , is a form of resistance to drugs by microorganism causing diseases such as bacteria and plasmodium. In this case, these microorganisms are able to survive even after they are exposed to one or more types of antibiotics. Majority of microbial are resistance to a particular type of antibiotics. However, there exist some bacteria that are resistance to numerous antibiotics. Collins (2002) describes them as MDR (multidrug resistant) or superbugs. Multiple researchers have categorized drug resistance as either induced genetic mutation or spontaneous....
