The man who is able to protect your information
By Jose Manuel Vera, One Hacker Magazine
One of the greatest experts in encryption, the technology that prevents your information from theft…. or from one being spied, talks to One Hacker. In fact, the encryption is critical for the security of our world from calls between individuals and messaging services to banking, military communications…
Realsec is one of the companies based in Spain which knows more about encryption. The technology that allows you to encode messages, data and images to protect them from espionage or to fall into the wrong hands. It’s the future ‘technological gold’ and thanks to it, we can securely enjoy all kinds of services in cyberspace. Jesús Rodríguez, Realsec CEO in Spain, is one of the references in this field.
You work with encryption technology, what is that exactly?
To encrypt the information means to encode it – to make it non-accessible, so it can only be read or decoded by those that posses the key to do it. The information can be encoded using different algorithms or encryption methods and its greatest or least strength lies in the means used to encrypt.
Hardware-based encryption is much more robust than the software-based encryption. This is determined mainly for two reasons: the first one is because the keys are housed in repositories that are not removable and the second one is that the mathematical calculation is performed in hermetically shielded memories.
When people hear the word encryption, they think about something strange and complicated… For many years cryptography and encryption have been linked to the defense and intelligence world. Today, we live in a digital world, full of threats and vulnerabilities and we need to be aware of the importance and need to protect our identity and privacy as well as our individual and collective rights, our heritage and the defense of our nation; without forgetting that we live in a world more connected and global that is necessary to defend and preserve oneself from cyberattacks and cyberthreats of this new era.
What three big challenges are you considering in this field for the coming years?
We believe in enhancing and adapting our technology for the fight against fraud and ensuring payments in Internet – in order to increase the consumers’ confidence in online transactions as well as meet the European regulations -, adapt it to mobile devices and go on working in the encryption applied to cybersecurity and cyberdefense.
The most curious thing about this technology…
Spain has developed solutions that are known to be outstanding worldwide.
Realsec works in order to protect the banking. Is it doing enough to protect it?
Yes, we have a large number of financial institutions as clients in Spain – and abroad -. It is one of the sectors that invests the most in a lot of resources such as in the risk prevention and eradication of cyberattacks as well as in the fight against fraud prevention. However, they are quite discreet when it comes to announcing incidents.
It seems that banks suffer few attacks…
I think it is wiser to focus on preventing the risks and fight and mitigate cyberattacks rather than give them publicity. In these situations, advertising tends to generate distrust or panic in customers and motivation, if not glory, within cybercriminals.
Your technological dream as an expert in this field…
Develop more powerful algorithms in cryptography – for example the quantum – and moreover, be able to guarantee the absolute confidentiality of the information stored or transmitted.
A tip for living cybersecure…
It is essential that the keys used to encrypt or sign digitally are kept properly and make sure that they are not stored in containers that can be accessed by third parties; likewise, we must never provide our keys to third parties.
The last attack that has surprised you…
Not one can leave you without any astonishment at all, and we could mention several. But in particular, we have two very recent ones. Last February, a hospital in Hollywood as well as two other German hospitals, were victims of an attack by malware called “ransonware”, an attack which blocked all their files and completely paralyzed the activity of these hospitals. The modus operandi in these cases is that cybercriminals do not release the encrypted data until they have charged a reward.
What are the big threats for the coming months?
Those who work in the security field have assumed that 100% security is an utopia. Thus, the greatest concern for 2016 will be the industrial cyberespionage to commercialize with the stolen information. Furthermore, an increase of attacks is expected on mobile devices, such as smartphones, with special attention to the new payment systems. Finally, there will also be a growth of cyberterrorism focused in strategic sectors and critical infrastructures.
And in the future…
Cybercrimes related with the impersonation and use of identity data will increase, especially those aimed to mobile devices -Android and iOS-. In addition, cyberattacks will grow against small and medium-size enterprises and to medium-long term to interconnected devices – Internet of Things-.
