PKC & PKI
Genus One can provide the specialist skills to develop software for secure communcation devices. We have developed embedded and PC-based software for both commercial and public-sector use and have a firm understanding of modern cryptographic techniques and secure system design.

Most of us regularly use SSL (https) to access secure websites for banking or e-commerce and we use encryption (without knowing it) when we make mobile telephone calls, but very few people protect the sensitive information they often send in emails.
Until now there have been relatively few serious email encryption products available. PGP and its open source variant, GPG, have under-pinned most of these products, but they all suffer from something I call the PKI problem: If you want to send a message to someone else, apart from installing the software yourself, you also have to get your recipient to install their software and to tell you their (authenticated) public key. Now, there is an alternative: Identity-based encryption.
In an identity-based system, a recipient's public key is effectively just their identity. To send an encrypted email, you just encrypt and send it. And your recipient doesn't even need to have installed the software, let alone generated any keys. Only when they receive your message do they need to perform a once-only set-up, authenticating their identity with a trusted central authority, and obtaining their unique decryption key.
One of the first products to exploit this new cryptographic technique is Private Post from Identum Limited. The product is free for non-commercial use so if you want to start protecting your sensitive data in emails, try it now.
