Kyber is a key encapsulation mechanism (KEM) designed to be resistant to cryptanalytic attacks with future powerful quantum computers. It is used to establish a shared secret between two communicating parties without an ( IND-CCA2 ) attacker in the transmission system being able to decrypt it.
An IDS must be aware of all of the possible encodings that its end hosts accept in order to match network traffic to known-malicious signatures. [1] [2] Attacks on encrypted protocols such as HTTPS cannot be read by an IDS unless the IDS has a copy of the private key used by the server to encrypt the communication. [3]
Relay station attack. Two relay stations connect over a long distance the owners transponder with the cars transceiver. A relay attack (also known as the two-thief attack) [1] in computer security is a type of hacking technique related to man-in-the-middle and replay attacks. In a classic man-in-the-middle attack, an attacker intercepts and ...
Tamperproofing is a methodology used to hinder, deter or detect unauthorised access to a device or circumvention of a security system. Since any device or system can be foiled by a person with sufficient knowledge, equipment, and time, the term "tamperproof" is a misnomer unless some limitations on the tampering party's resources is explicit or assumed.
Because side-channel attacks rely on the relationship between information emitted (leaked) through a side channel and the secret data, countermeasures fall into two main categories: (1) eliminate or reduce the release of such information and (2) eliminate the relationship between the leaked information and the secret data, that is, make the leaked information unrelated, or rather uncorrelated ...
In cryptography, a timing attack is a side-channel attack in which the attacker attempts to compromise a cryptosystem by analyzing the time taken to execute cryptographic algorithms. Every logical operation in a computer takes time to execute, and the time can differ based on the input; with precise measurements of the time for each operation ...
Note that security depends also on the resistance of the blinding functions themselves to side-channel attacks. For example, in RSA blinding involves computing the blinding operation E ( x ) = (xr) e mod N , where r is a random integer between 1 and N and relatively prime to N (i.e. gcd( r , N ) = 1) , x is the plaintext, e is the public RSA ...
A Byzantine fault is a condition of a system, particularly a distributed computing system, where a fault occurs such that different symptoms are presented to different observers, including imperfect information on whether a system component has failed.
