Parsec soon to launch cryptographic high security IDs

Parsec_SecIDCyber security is a matter of serious concern in light of the immense threat of unauthorised access to industrial, commercial, governmental and personal data. Parsec has been working on a most cost-effective solution, which could go a long way to counter this threat.

“We believe the USB cryptographic tokens, otherwise known as HSIDs (high security IDs), developed by Parsec, will find ready application throughout industry, especially the retail and banking sectors,” says Tobie van Loggerenberg, director of Parsec. “But, it goes much further: these devices are ideal for government and defence, whose mandate is national security and whose imperative it is to continuously elevate cyber protective measures.”

According to Van Loggerenberg, the requirements of the Protection of Personal Information Act (Act No 4 of 2013) places distinct demands on public and private corporate entities to protect personal information, which could be addressed with the HSID token.

“The HSID offers security features that will be of great benefit to these entities.”

The HSID has the appearance of an ordinary flash memory stick, albeit one with significantly more advanced application due to its sophistication. In essence, it provides hardware security for encryption keys, certificates and algorithms. Moreover, this is coupled to the enforcement of a second factory of authentication, similar in some respects to the process where banking transactions are authorised by means of one-time PINs.

“It works as follows: two-factor authentication means that the bearer of the token has to be in physical possession of the token, and at the same time, has to know the token’s PIN,” Van Loggerenberg explains.

Even with the token in hand, and simultaneously ignorant of the PIN, it is not possible to gain access to the stored keys and functionality. “Not only does this prevent unauthorised access to sensitive information, but the HSID is immune to common attacks like phishing or key-logging.”

Parsec sees further typical applications of the HSID in encryption of disks, files and e-mails, password storage, random number generation and digital certificates. All these functions are performed internally in the token. This is particularly important to businesses and individuals, who are targeted on a daily basis, often with huge financial – and reputational – damage.

Online security has become a constant in our lives. The Parsec developed range of HSID tokens represents an ideal and cost-effective solution. For users across the broad spectrum of online services, it has the advantage of being supported on all Microsoft Windows and OS X operating systems. The tokens are easy to install and use.

“Parsec is already taking its HSID5000 model through FIPS 140-2 level 3 validation, which goes to show that we take cyber security very seriously,” Van Loggerenberg concludes.

Sentinel Gas Detection system takes mine safety to a higher level

A case study about the development of a gas detection system and support equipment and the integration into the Schauenburg Flexaducx Mine-Wide Integrated Monitoring and Control System

By Tobie van Loggerenberg, Business Development Director, Parsec

Safety, where people are involved, is very important. This is even more important for the mining industry where the mines are legally obliged to guarantee the safety of their employees despite the numerous risks associated with the working environment.  An integrated safety system ensures information sharing between sub-systems enabling effective warning and control without delay.

Schauenburg Flexadux (www.schauenburg.co.za), a company specialising in the supply of safety equipment for mining had a concept in place of a distributed monitoring and control system called MIMACS (Mine-Wide Integrated Monitoring and Control System) but lacked  a modern automated solution for gas detection which is required to meet the SANS 1515 standard as adopted by the SABS in 2006. The company approached Parsec to develop such a system and ensure compliance with the SABS standard.

This case study describes the development of the Sentinel GDI (Gas Detection Instrument) for detecting and reporting of hazardous gas concentrations present in work areas in mines. The device collects data from various on-board sensors, displays the concentration values on a built-in screen and logs it to an internal non-volatile memory. This data can be retrieved from the instrument by means of a wireless communication link. Sentinel Gas detection system-1

The development of the prototype by the previous development partner was plagued by many problems. This put Schauenburg in a difficult position as their marketing efforts for the new GDI had created anticipation in the industry and lined up clients, but the product was not ready. The opposition also had new instruments in the pipeline and Schauenburg was pressured to not only keep their market share, but also expand on it.

The objective for Parsec was to develop and certify the GDI in as short a time frame as possible, produce a design with maximum flexibility and have remaining capacity for future expansion.

Due to short timescales, the project was approached concurrently from three sides. Firstly, the instrument itself needed redesign in order to achieve SABS certification. Secondly, the support equipment which addressed charging, calibration, testing and configuration was also required during the certification process. Thirdly, the software for the instrument, tester/calibrator and configuration was needed at the end of the certification period.

Temporary low level software was used during certification in order to verify the critical gas measurement hardware also giving the software team more time to develop the final application with a friendly, aesthetically pleasing user interface with extensive capabilities.

Major Challenges to overcome from the prototype baseline

 

Parsec started with a partly developed prototype baseline. The mechanical parts were already in an advanced stage of development and it was decided not to make dramatic changes to the mechanics due to negative knock on effect of costs and time to market. The electronics were plagued by various issues like inefficient power conversion, excessive temperatures on the charge stations, non-functional wireless communications, high current spikes blowing the Intrinsic Safety fuses and noisy analogue circuits.

Successes

The battery life that previously lasted less than eight hours on a full charge was extended to eighteen hours with all sensors fully activated and the display continuously switched on. This ensures the safety of personnel even in the event that a double shift needs to be completed underground.

A configurable analogue-front-end was implemented making it possible to accommodate different configurations of gas sensors without the need for physical change of components on the PCB.

Wireless communications by means of an 868 MHz radio makes it possible to exchange data with a management server. Logged data can now be uploaded to the server from where reports are generated on request. Software and setting can also be managed and downloaded to an individual or multiple instruments simultaneously.

Contactless inductive charging runs reliably and fully charges a drained battery in less than eight hours.

Automatic calibration and test stations were implemented requiring no user intervention of the process. Multiple stations in a single area testing multiple instruments simultaneously is now possible. Log and upload of results from the test stations to the server makes it possible to audit test & calibration procedures on any instrument at any time.

The instrument achieved SANS 1515 certification on 23 December 2011.

Parsec prides itself on its ISO9001 accredited processes which guided this project through the different phases of its lifecycle. Regular communication with the customer also proved helpful to manage expectation on progress and delivery.

Conclusion

Through developing the Sentinel GDI and support equipment, Parsec learned valuable lessons including the importance of de-risking throughout the project lifecycle. It is important to validate each sub-system as soon as possible and identify potential problems.   It has proven our ability to supply a customized all-inclusive solution to our customer. The company is well positioned to be involved in the subsequent development of mine related safety equipment and infrastructure.
