For companies moving to public or even multicloud environments, key management and encryption — of data in motion, at rest and even in use — are top of mind. Organizations consider certificate management and key management a commodity, and many seem to struggle to get this right.
However, there’s more to cryptography than encryption, keys and certificates.
What Is Cryptography and What Does It Do?
Cryptography is a set of techniques for securing communication and, in general, data. As one could infer from the name — in Greek, kryptós means “hidden, secret” and graphó means “to write” — cryptography’s original purpose was to keep data confidential. After more than four decades of modern cryptographic research and development, the objective has expanded to also address data integrity, privacy, availability and nonrepudiation.
Beyond encryption, cryptography provides techniques for digital signing, secret sharing among parties that do not trust each other (multiparty computation), searching through and computing on encrypted data (fully or somewhat homomorphic encryption), zero-knowledge proofs, tokenization, quantum-safe crypto algorithms, and more.
Deploying enterprise-scale cryptography can be a challenge; while the adoption and practical use of crypto technology is becoming increasingly simple, there is a shortage of knowledge and skill in this space, which limits its scale and proliferation. To overcome these challenges, organizations need a strategy that combines the right skills, governance and a sound operating model underpinned by accredited technology solutions.
Why Do Companies Need Cryptography Services?
Cryptography is everywhere, which means managing crypto is a decentralized capability. By everywhere, I mean literally across all platforms and the whole IT stack. We find implementation of cryptographic algorithms in all our products, including ha ..
