Is your business utilizing a public cloud infrastructure and striving to secure data from cloud service providers and other shared teams? If so, Bring Your Own Key (BYOK) is for you. Designed as a security model to allow organizations to gain control over data security.

What is Bring Your Own Key (BYOK)?

BYOK is an enhanced encryption practice where organizations have the ability to encrypt and decrypt data as per their needs and requirements. In simple terms, think of BYOK as a rental space where you have access to everything except ownership of the key.

Unlike traditional models where cloud service providers generate and store encryption keys, the BYOK gives organizations the ability to create, generate and manage encryption keys that are used to secure and protect their data. While organizations need to transfer the encryption key to the respective cloud service providers, it makes no difference as the organization holds the responsibility for key management operations like monitoring BYOK key rotation frequency, managing key distribution phases, and streamlining key revocation procedures.

With the BYOK solution, organizations can protect their sensitive data and applications by segmenting them even in third-party infrastructure, as they have complete control over encryption keys. While its uses, cases and benefits are many, let us first explore a little history and evolution of BYOK encryption.

History and Evolution of Bring Your Own Key

The practice of encryption dates back to ancient times, when the need to protect and safeguard sensitive information arose. It started as a practice,

In Egyptian civilization, encoding educational, religious, and taboo practices was documented in secretive ways, requiring specific deciphering skills to interpret them.
Later, the Greeks utilized this approach to hide military communications through a device known as the scytale, which involved wrapping a strip of parchment around a staff to reveal a message only readable on a matching staff, introducing the concept of a shared secret key.
World War II changed the course of encryption, as it was the beginning of machine encryption. It was during this time that computers came into existence. The encryption created using those computers would require trying nearly 17,000 combinations.
The rise of World Wide Web gave birth to today’s modern cryptography, the RSA algorithm in 1970, which had two encryption keys, one private and one public, underpinning the security of digital communications. Thus, this marks a significant evolution for today’s advanced encryption models, like BYOK.
