Encryption can be traced back to the hieroglyphics of ancient Egypt around 3000 B.C. Long-considered impossible to decipher, the discovery of the Rosetta stone was the key to breaking the code.

During the Middle Ages, growth in diplomatic activities increased the need to convey confidential information, giving rise to the famous Cipher of Mary Queen of Scots and many others.

With the advent of the Internet and the vast amount of confidential information now exchanged, encryption technologies have become part of everyday life for everybody.

Quantum computing will shatter RSA/ECC encryption standards. It’s only a question of when. To stay ahead of the curve, we’re testing post-quantum cryptography in hybrid certificates to provide protection from both standard and quantum attacks.

Start testing post-quantum secure certificates today to keep your data safe tomorrow. DigiCert's post-quantum cryptographic (PQC) toolkit contains everything needed to create a hybrid TLS certificate. This hybrid certificate uses a post-quantum cryptographic algorithm paired with a classical cryptographic algorithm, allowing you to test the viability of deploying post-quantum hybrid TLS certificates while also maintaining backwards compatibility.

Gartner predicts there will be 25 billion connected devices by 2021. This is an unprecedented number of smart devices - exceeding the number of cellphones and computers in the world today - which will enable new efficiencies, communication methods, and modes of commerce. New technologies also mean new threats to data security, users, and enterprises.

DigiCert's IoT Public Key Infrastruture (PKI) platform is a proven comprehensive solution purpose-built for IoT efficiency, automation, and high performance. DigiCert provides management capabilities and data security protection for smart devices, industrial sensors, manufacturing systems, and healthcare devices.

TLS (Transport Layer Security)/SSL (Secure Sockets Layer) technology enables the world to engage in online communications and ecommerce with confidence. Without it, sensitive information such as credit card numbers and passwords travelling between the user and the destination server could be seen by another computer. Three types of validation method are used: DV (Domain Validation), OV (Organization Validation) and EV (Extended Validation), with EV certificates providing the maximum amount of trust to visitors.

Each TLS/SSL certificate consists of a key pair as well as verified identification information. When a web browser points to a secured website, the server shares the public key with the client to establish an encryption method and a unique session key. The client confirms that it recognizes and trusts the issuer of the certificate. This process begins a secure session that protects message privacy and message integrity.

TLS/SSL also provides assurance, as browsers use visual aids such as lock icons or a green bar to tell visitors that their connection is secured by a TLS/SSL certificate and that it is safe to transact.

RSA and ECC are currently standard encryption algorithms used in TLS/SSL certificates.

In the near future, experts such as NIST have stated that the public-key cryptography used today will be broken by large-scale quantum computers, putting privacy and security at risk. Connected devices are on the rise (25 billion by 2021), many of which will have a long life span and as such post-quantum computing (PQC) is going to be a crucial element to consider when securing them. Additionally, we have identified that securing business infrastructures against threats rooted in today’s technology is not enough; a good example of this are financial institutes with their growing user base and demand for higher security.

DigiCert is finalizing its product plan to release a solution which is capable of offering RSA-ECC (hybrid) and PQC algorithms as part of a hybrid X509 certificate. This will protect web servers and IoT devices against the threat that quantum computers are going to pose. Adding PQC to our solution is part of our commitment to take care of our customers and innovate to solve future security challenges.

A common goal for most companies is to improve business agility. The ability to quickly adapt to market changes gives an organization a competitive advantage and can also prevent unnecessary loses.

Information is an organization’s lifeblood, and the information security department is responsible for establishing and maintaining secure connections between IT systems and all external devices. As a best practice encryption should always be used between diverse systems that have to interoperate.

Your organization should require encrypted links to protect the information in transit whether it is destined for internal or external systems. As the sheer number of connected devices continues to rise, becoming “crypto agile” is a key component of an organization’s business agility.
