The Web Cryptography API can enhance the security of messaging for use in off-the-record (OTR) and other types of message-signing schemes through the use of key agreement. The message sender and intended recipient would negotiate shared encryption and message authentication code (MAC) keys to encrypt and decrypt messages to prevent unauthorized ...
Internet security is a branch of computer security. It encompasses the Internet, browser security, web site security, [1] and network security as it applies to other applications or operating systems as a whole. Its objective is to establish rules and measures to use against attacks over the Internet. [2]

For example, Transport Layer Security (TLS) is a cryptographic protocol that is used to secure web connections. [2] It has an entity authentication mechanism, based on the X.509 system; a key setup phase, where a symmetric encryption key is formed by employing public-key cryptography; and an application-level data transport function. These ...
Information security is the practice of protecting information by mitigating information risks. It is part of information risk management. [1] It typically involves preventing or reducing the probability of unauthorized or inappropriate access to data or the unlawful use, disclosure, disruption, deletion, corruption, modification, inspection, recording, or devaluation of information.
The question of balancing the need for national security with the right to privacy has been debated for years, since encryption has become critical in today's digital society. The modern encryption debate [42] started around the '90s when US government tried to ban cryptography because, according to them, it would threaten national security ...
This is a trade-off between security and availability: failing-soft allows downgrade attacks, while failing-hard allows denial of service (from attacks) or causes unavailability. [ 18 ] An attacker with the ability to present a compromised certificate likely also has the ability to prevent the client performing an online revocation status check ...
Open Discussion Encourages Better Security The long history of cryptography and cryptoanalysis has shown time and time again that open discussion and analysis of algorithms exposes weaknesses not thought of by the original authors, and thereby leads to better and more secure algorithms.
