The world of cybersecurity is fast paced and ever-evolving and a lot can change in a year or two. Here we take a look at some of the latest developments in encryption technology.
Transport Layer Security Version 1.3 is Completed
Last year, Transport Layer Security (TLS) version 1.3 was at last finalised. TLS is now one of the most widely used cryptographic protocol to prevent eavesdropping and tampering, and after many years of research the cryptographic element of its latest design is now complete.
TLS 1.3 support was introduced to Google Chrome for Linux, macOS and Windows in January 2017, with Android and iOS following a few days later. The major redesign, which comes 8 years after the release of TLS 1.2, will considerably speed up processes and reduce the number of network round-trips, meaning latency will decrease and pages will load faster.
TLS 1.3 is not just a pace improvement, but it’ll also have enhanced security. It was extensively trialled and analysed by the cryptographic community during the process and used model checking to highlight any flaws.
Post-Quantum Cryptography Has Become a Key Concern
For many years, experts have been pondering the idea of what happens once quantum computing becomes a reality, however only recently has this research become a main focal point.
Dr Tanja Lange, chair of the Coding Theory and Cryptology group at Technische Universiteit Eindhoven and coordinator of the European project PQCRYPTO, said:
“everything encrypted today must be considered compromised once a quantum computer exists.”
And in February 2016, the National Security Agency released a statement:
‘There is growing research in the area of quantum computing, and enough progress is being made that NSA must act now’
Although no one knows when a quantum computer will be invented, Google has already begun experimenting with quantum-resistant algorithms in Chrome and we predict many more reports of commercial solutions to future-proof data protection from quantum threats to appear over the next 12 months.
Homomorphic Encryption Is Still Being Researched
Homomorphic encryption – a crypto system that utilises ciphertext and allows operations to be performed without compromising encrypted data.
Homomorphic is slow and processor intensive, and there has even been an instance where an MIT scheme was publicly cracked. Despite this, a number of startups created by Silicon Valley venture capitalists are investing considerable time and money into this.
Although no major developments have been announced yet, expect to see it being launched later in the year.
Do You Need Secure Messaging Services?
Confidential workflows require secure messaging with enhanced encryption so that your transmitted data has an added level of protection and ensures you’re protected should you suffer a security breach.
