Polin: „Ultimate Lost Object”

Lost in Object Space

The functionality in object-oriented programs is fragmented in its objects. Composing the whole functionality of such a program out of the functionality of the objects is not a trivial task. Furthermore, the role that objects play during the execution is for many students unclear. Consequently many novice students suffer from the ”lost in object space” phenomenon. In this paper we present an en...

Planck Scale Physics and Newton's Ultimate Object Conjecture

According to Newton, the ultimate building blocks of matter are hard frictionless spheres. This conjecture is here analyzed under different assumptions, which are: 1. The ultimate objects of matter are frictionless positive and negative Planck mass particles obeying nonrelativistic Newtonian mechanics. 2. The Planck mass particles interact with the Planck force c/G (c velocity of light, G Newto...

Lost iPhone? Lost Passwords!

The paper highlights risks that accompany losing a locked iOS device regarding confidentiality of passwords stored in the keychain. It presents results of handson tests that show the possibility for attackers to reveal some of the keychain entries. For the described approach, the knowledge of the user’s secret passcode is not needed, as the protection provided by the passcode is bypassed.

Ultimate Cloud

One of the supreme perplexing problems of cloud service provisioning is to motivate users to believe and to trust the security of cloud service and upstream their sensitive data. Even though cloud service providers can say that their services are heavily protected by extravagant encryption methodologies, modern cloud systems still cannot convince the users that even if the cloud servers are exp...
