The cryptographic protection of a system against attacks and malicious penetration depends on two dimensions: (1) The strength of the keys and the effectiveness of mechanisms and protocols associated with the keys; and (2) the protection of the keys through key management (secure key generation, storage, distribution, use and destruction).

This article introduces and classifies cryptographic key types and crypto-periods as suggested by NIST, based on proven best practices for key management. It outlines the recommendations of when and how keys are used to protect data and explains how appropriate crypto-periods can be chosen and enforced.

This article discusses the benefits eIDs provide for both banks and customers in streamlining cross-border transactions and what is required under eIDAS for identity verification and client onboarding.

The concept of a token has been used in the digital world for almost 50 years to separate and protect real data elements from exposure. In recent times, the concept of tokenization has been used as a security mechanism for protecting sensitive data.

The protection and secure management of cryptographic keys is crucial for ensuring that cryptography is used in the most effective way to keep data secure. Picking the wrong key management system (KMS) can thwart all the efforts that have been made in using cryptography to protect information.

Credit cardholders are generally protected from liability if unauthorized transactions are made with their credit cards because of consumer protection laws and card policies. This leaves merchants and financial institutions on the hook for losses related to credit card fraud. According to an October 2016 Nilson Report, card issuers were burdened with 72 percent of fraudulent losses in 2015 while merchants were left with 28 percent of the losses.

This article summarizes the basic cryptographic security services that can be used to protect information (or as a supporting protective mechanism) against attacks, as described in the NIST Special Publication 800-57 (1, rev.4) for Key Management.

EMV chips on payment cards contain cryptographic co-processors and dual interfaces that allow for contact and contactless payment options. When issuing an EMV card, the customer’s information is extracted from the bank or financial institution’s database.

The World Wide Web Consortium or W3C as it is commonly known was founded in 1994 by the original architect of the World Wide Web, Tim Berners-Lee. It is a consortium of international companies that are involved with the Web and the Internet.
