Computers communicate with each other daily via direct connections, which creates the need for strong data security. Modern-day applications of cryptography are seen in e-commerce, banking systems, military communications, and basic user-to-user messaging. Implementing data encryption and cryptographic ...
Cryptography is the process of hiding or coding information so that only the person a message was intended for can read it. The art of cryptography has been used to code messages for thousands of years and continues to be used in bank cards, computer passwords, and ecommerce. ...
Cryptology, which encompasses both cryptography and cryptanalysis, is deeply rooted in computer science and advanced mathematics. The history of cryptography dates back to ancient times when Julius Caesar created the Caesar cipher to obscure the content of his messages from the messengers who carried th...
Infineon is a pioneer in the development and implementation of cryptographic mechanisms that can withstand the processing powers of quantum computers. By preparing for a smooth transition from currently used security protocols to post-quantum cryptography (PQC), Infineon enables robust and future-proof ...
Present-day computer security is a house of cards; it may stand for now, but it can’t last. Many insecure products have not yet been broken because they are still in their infancy. But when these products are widely used, they will become tempting targets for criminals. The press will ...
Building a secure cryptographic system is easy to do badly, and very difficult to do well. Unfortunately, most people can’t tell the difference. In other areas of computer science, functionality serves to differentiate the good from the bad: a good compression algorithm will work better than ...
In this U.S. presidential election year, public attention is focused upon voting technologies. As we struggle with options, the pendulum swings between hand-counted paper, which is cumbersome and subject to mishandling; lever machines, which can be manipulated by knowledgeable insiders; punch cards...
Chapter 4. Cryptography One of Ethereum’s foundational technologies is cryptography, which is a branch of mathematics used extensively in computer security. Cryptography means “secret writing” in Greek, but the … - Selection from Mastering Ethereum
