The simplest such pairwise independent hash function is defined by the random key, key = (a, b), and the MAC tag for a message m is computed as tag = (am + b) mod p, where p is prime. More generally, k -independent hashing functions provide a secure message authentication code as long as the key is used less than k times for k -ways independent ...
[24] It recommends cryptographic erase as a more general mechanism. According to the University of California, San Diego Center for Magnetic Recording Research's (now its Center for Memory and Recording Research) "Tutorial on Disk Drive Data Sanitization" (p. 8): "Secure erase does a single on-track erasure of the data on the disk drive. The U ...
Encryption with key erasure involves encrypting all sensitive material in a way that requires a secure key to decrypt the information when it needs to be used. [14] When the information needs to be deleted, the secure key can be erased. This provides a greater ease of use, and a speedier data wipe, than other software methods because it ...
Crypto-shredding or crypto erase (cryptographic erasure) is the practice of rendering encrypted data unusable by deliberately deleting or overwriting the encryption keys: assuming the key is not later recovered and the encryption is not broken, the data should become irrecoverable, effectively permanently deleted or "shredded". [1]
MacKeeper's usefulness was disputed by tech media; anti-malware, secure erase, backup, encryption, and anti-theft were either built-into macOS or available for free. [ 6 ] [ 31 ] Top Ten Reviews noted that other Mac anti-malware apps had better detection rates, resulting in a score of 7.5 out of 10. [ 32 ]
1. Delta Air Lines. On-Time Arrivals: 83.46% Delta took the top spot in the report for the impressive fourth year in a row. Sure, there’s always going to be unforeseen delays in a trip, but if ...
The NHTSA's Office of Defects Investigation said it had received one complaint alleging a crash when the feature was being used and had reviewed at least three media reports of similar crashes ...
