Fully Homomorphic Encryption

- hype or the answer to all our prayers?

A couple of years ago, Craig Gentry produced a break-through result in cryptography: what researchers had been dreaming about for more than 25 years was finally possible: Gentry had shown how to do so-called Fully Homomorphic Encryption (FHE). What this allows is for a party A to receive encryptions of a set of inputs to some computation. A does not have the key for decryption and so has no idea what the inputs are...

Q: What's in a Logo? A: Mathematics

Maybe you have wondered where our logo comes from and what it actually means. If you have, we hope the following will answer these questions.

Just as our name suggests, mathematics is the strong foundation on which our company has been built. The same applies to our logo. The Cryptomathic logo is a 4D (4-dimensional) cube projected onto a 2D (2-dimensional) plane, with one 3D (3-dimensional) cube highlighted. However, we, as terrestrial ...

Delivering Advanced Electronic Signatures - via a central signing server

The notion of Advanced Electronic Signature was introduced in the European Directive for electronic signature, which remains today an important milestone for the standardization and legal recognition of electronic signatures. Advanced Electronic Signatures (hereinafter AdES) offer a very practical method to protect information and provide trust in electronic business. They can be embedded in popular document formats such as PDF, XML and CMS messages  and are also the base stone for creating qualified electronic signatures (QES)

Art. 2 of the directive contains some requirements on signatory identification and. This paper describes how a central signature server can fulfill these requirements. This article relates to the European Commission Standardisation mandate m460 to CEN and ETSI on electronic signatures and is proposed as input for the ETSI standard prTS 14167-5.

EMV: The Fraud Bulldozer

These days everyone has a stake in Chip and PIN security - it can be the topic of the over-the-counter conversation as you pay, of the boardroom executives at a bank, or over a pint at the pub. So how is EMV, the electronic payments standard underlying Chip and PIN shaping up? And what is the modern landscape of payments fraud? Here, Mike Bond, Technical Director at Cryptomathic, shares his opinion.  

Where 2FA and PKI Meet

Under pressure from sophisticated attacks and rising fraud, many B2C organisations of the financial industry are currently enhancing the static password based authentication to their web applications to something stronger - the 2FA age. 2-Factor Authentication (2FA) is currently achieving large scale deployments and consumer adoption where PKI failed a few years ago. From a technical standpoint, PKI offers significant benefits including the possibility to sign tra...
