A collection of cryptographic articles and resources3rd Party TSM Management of SIM Cards
Trusted Service Manager (TSM) is a relatively new role required in a mobile Near Field Communication (NFC) ecosystem. The core services a Trusted Service Manager offers, are the secure management and provisioning of the applications issued by service providers, such as banks, transport / ticketing authorities, merchants, or other application issuers. Provisioning performed over the air (OTA) includes, for example, the download, installation, personalization and life-cycle manageme...
Read MoreAre the Dynamics of Card Fraud Changing?
In 2009, the RBS WorldPay ATM network reportedly lost $9 million to a 30 minute fraud attack across 49 cities, in different countries, using just 100 cloned cards. On the face of it, the $9 million dollar yield from the attack is a large enough figure to make headline news, but perhaps not that shocking in this day and age where the total UK card fraud exceeded £500 million in the past year, according to APACS figures. What is possibly more serious in this particular scenario is t...

Cryptomathic NewsOnInk, 2008This article provides an overview of GlobalPlatform (GP) Key Management and includes a proposed architecture for an efficient GP Key Management System (KMS) based on the Cryptomathic Key Management System (CKMS). This article is not intended to cover all possible uses of GlobalPlatform, but is meant to provide an overview of how it may well be used in an environment where the chip is personalized centrally, after which it is delivered to the end-user and subsequently updated with new appl...

Ever since the EU mandated the introduction of biometric ePassports containing fingerprints there has been a flurry of technology development and innovation to make biometric ePassports a reality. Much of this played out behind the scenes, but now electronic passports are slowly working their way towards the forefront of the public consciousness since they are sufficiently widespread for researchers and journalists to play with. There have already been a number of security scare s...
Read MoreThe Trusted Platform Module Explained
Introducing the TPM The Trusted Platform Module (TPM) is a special purpose microcontroller designed by the Trusted Computing Group, which interfaces with a standard hardware/software platform in order to allow it to be secured to serve the interests of just one party - the system designer. The current generation of TPMs (version 1.2) are stand-alone chips which are usually surface mounted onto the motherboard of a PC, or integrated in...
