Field tests of remote applications and file management on the SIM via BIP

2011-07-15T23:04:00.005+04:00

Although BIP support (stands for Bearer independent protocol) used mostly to access remote resources from SIM card using packet data interfaces such as GPRS was implemented quite a while ago in our CellSIM operating system we have never had a chance to test it in field. All previous tests were only done in a normal card reader.

Today we did real tests using BIP managing (U)SIM card remotely: application download and installation, file management etc. Speed compared to SMS based transport was really a fun.

This is quite sad that not so many handsets, especially mainstream like Android or iOS support such a feature. Let's hope that support for BIP will be integrated into RIL library of Android in the nearest future.

We will speak at Smart Event 2009 on the following topic "Reverse engineering of Java Card applications: a real thread or a challenge?"

2009-07-29T16:51:00.001+04:00

CAP file is a common binary redistributable in the Java Card world which contains all required information for a smart card manufacturer to be able to upload the third party application onto the SIM and deliver the final product. Such scenario is quite common for mobile applications which are usually provided by one smart card vendor or by an independent company and distributed to all vendors wishing to deliver SIM cards to an operator or just to take part in a preliminary testing. Therefore, quite often such an applet may fall into hands of competitors. Owing to the growth of the Java Card application market and the increasing size and complexity of the applications itself such thread should carefully considered.
It is known that interpreted Java byte codes are quite vulnerable to reverse engineering attacks which can be performed even with the open source java decompilation tools unless the compiled code underwent obfuscation. Standard Sun’s converter normally employed for CAP generation works to a great extent as an obfuscator hiding class and field names as well as method signatures. Nevertheless, a CAP file generated by a common Sun’s compiler and converter can be reverse engineered and in most cases will remain compilable.
A proposed by the authors CAP decompilation technique is a two stage process. At first step class files are reconstructed from the original CAP using the reversed procedure followed by the common converter, then, source codes can be recovered using available open source tools such as JAD. The reconstructed code misses original class, method and field names and its analysis itself can be a challenge, however, it can be used for certain operations. The proposed technique is sensitive to java compiler and converter versions used for the original compilation. Therefore certain counter-measures implemented in the converter such as flow or stack operations obfuscation can prevent from the correct code reconstruction.
The presented results demonstrate that vulnerability to reverse engineering attacks should be seriously considered by Java Card developers intending to distribute their applications to the third parties especially for Java Card 3.0 platform.

Developing real-world smart card web server applications

2009-06-26T23:50:00.004+04:00

Cellnetrix took part in the 2nd Comprion technology day in Paderborn, Germany with a presentation related to smart card web server technology. You can check out the presentation Developing smart card web server applications

Cellnetrix will speak about its first experience on SCWS service development at 2nd Comprion technology day on June,23rd

2009-06-05T13:04:00.001+04:00

Smart card web server technology is gaining momentum and becomes more and more important both for mobile operators and the mobile services community. First mobile handsets supporting this functionality appeared on the market. Although it will probably take 1 or 2 years until there is a significant subscriber base with the right phones, SCWS service development should be strongly considered already today. Cellnetrix as an expert in mobile security and smart card software will present first results of SCWS services implementation on the 2^nd Comprion technology day in Paderborn, Germany, on 23^rdJune (http://tinyurl.com/oufuer).

Cellnetrix starts its own blog

2009-05-12T23:16:00.008+04:00

At last we have managed it: found some spare time and started our official blog where would like to speak a lot about smart cards and secure devices, secure gadgets, their applications in various domains, first of all, in mobile communications and in Internet which our company focusing on.
We intend to share more information on our products and services, give unbiased view (why not!) on the latest industry developments and provide some insights into internal company life.
Security is becoming more and more important in those spheres where it is most required such as wireless mobility, on-line services, corporate/business applications. Not pretending to give a final solution or recipe we will discuss those issues from different aspects trying to understand where we are going and to find an answer together.

Any comments or ideas are very appreciated!

Vladimir.
