Given the computational limitations of IoT devices, smartcards, and mobile devices, which of the following digital signature algorithms would be the most efficient choice due to its smaller key size and lower processing requirements?

Key stretching is a cryptographic technique that enhances the security of sensitive data, such as cryptographic keys and passwords. It works by repeatedly applying a resource-intensive function or algorithm to the input data, thus increasing the computational effort required to derive the original key or password, which makes the data more resistant to brute-force, dictionary, or rainbow table attacks.

Which of the following is an example of a key stretching algorithm?

The term "Open public ledger" is used to describe a distributed database stored across multiple computers in a P2P network.

Blockchain technology is an example of:

Which of the answers listed below refers to a set of standards and specifications that define various cryptographic techniques, including formats for public keys, private keys, digital signatures, and digital certificates?

Which of the following defines a file format for storing and exchanging personal identity information, including private keys and digital certificates?
