Typically this will involve overwriting the data with zeroes, but in the case of some types of non-volatile storage the process is much more complex; see data remanence. As well as zeroising data due to memory management, software designers consider performing zeroisation: When an application changes mode (e.g. to a test mode) or user;
Data sanitization is an integral step to privacy preserving data mining because private datasets need to be sanitized before they can be utilized by individuals or companies for analysis. The aim of privacy preserving data mining is to ensure that private information cannot be leaked or accessed by attackers and sensitive data is not traceable ...
Even if you fix the issue(s) described in a maintenance template, the tag will remain in the article until you or someone else manually removes it. The mechanics of removal are usually as simple as clicking "Edit" at the top of the page or in the section involved (if you're not already in edit mode), removing the code that produces the display ...
A key encapsulation mechanism, to securely transport a secret key from a sender to a receiver, consists of three algorithms: Gen, Encap, and Decap. Circles shaded blue—the receiver's public key and the encapsulation —can be safely revealed to an adversary, while boxes shaded red—the receiver's private key and the encapsulated secret key —must be kept secret.
Data remanence is the residual representation of digital data that remains even after attempts have been made to remove or erase the data. This residue may result from data being left intact by a nominal file deletion operation, by reformatting of storage media that does not remove data previously written to the media, or through physical properties of the storage media that allow previously ...
The Electronic Key Management System (EKMS) is a United States National Security Agency led program responsible for Communications Security key management, accounting, and distribution. Specifically, EKMS generates and distributes electronic key material for all NSA encryption systems whose keys are loaded using standard fill devices, and ...
In some cases, it may be impossible to decrypt the data because the key has been lost, forgotten or revoked, or because the data is actually random data which cannot be effectively distinguished from encrypted data. A proactive alternative to key disclosure law is key escrow law, where the government holds in escrow a copy of all cryptographic ...
Public-key cryptography, or asymmetric cryptography, is the field of cryptographic systems that use pairs of related keys. Each key pair consists of a public key and a corresponding private key. [1] [2] Key pairs are generated with cryptographic algorithms based on mathematical problems termed one-way functions.
