The RSA problem is defined as the task of taking e th roots modulo a composite n: recovering a value m such that c ≡ m e (mod n), where (n, e) is an RSA public key, and c is an RSA ciphertext. Currently the most promising approach to solving the RSA problem is to factor the modulus n .
A hospital information system (HIS) is an element of health informatics that focuses mainly on the administrational needs of hospitals.In many implementations, a HIS is a comprehensive, integrated information system designed to manage all the aspects of a hospital's operation, such as medical, administrative, financial, and legal issues and the corresponding processing of services.
The RSA SecurID authentication mechanism consists of a "token"—either hardware (e.g. a key fob) or software (a soft token)—which is assigned to a computer user and which creates an authentication code at fixed intervals (usually 60 seconds) using a built-in clock and the card's factory-encoded almost random key (known as the "seed").
Ransomware – A form of malware that locks a user out of their system and prevents access to files. A message will pop up on a device stating that a specific payment must be sent to regain access.
A Cyber Security Management System is a form of Information security management system, particularly focussed on protecting automation and transport systems. [1] The EU Cybersecurity Act, of 2019, led to the creation of UNECE working groups which developed the Cyber Security Management Systems (CSMS) concept (and also an approach for securing over-the-air updates of vehicle systems), which ...
In cryptography, security level is a measure of the strength that a cryptographic primitive — such as a cipher or hash function — achieves. Security level is usually expressed as a number of "bits of security" (also security strength), [1] where n-bit security means that the attacker would have to perform 2 n operations to break it, [2] but other methods have been proposed that more ...
RSA enVision is a security information and event management platform, with centralised log-management service that claims to "enable organisations to simplify compliance process as well as optimise security-incident management as they occur." [60] On April 4, 2011, EMC purchased NetWitness and added it to the RSA group of products.
