In computer systems, an access token contains the security credentials for a login session and identifies the user, the user's groups, the user's privileges, and, in some cases, a particular application. In some instances, one may be asked to enter an access token (e.g. 40 random characters) rather than the usual password (it therefore should ...
The token is a reference (i.e. identifier) that maps back to the sensitive data through a tokenization system. The mapping from original data to a token uses methods that render tokens infeasible to reverse in the absence of the tokenization system, for example using tokens created from random numbers. [3]
The simplest security tokens do not need any connection to a computer. The tokens have a physical display; the authenticating user simply enters the displayed number to log in. Other tokens connect to the computer using wireless techniques, such as Bluetooth. These tokens transfer a key sequence to the local client or to a nearby access point. [4]
Token, a voucher or gift card redeemable for items of value Token coin , a small, flat, round piece of metal or plastic that can sometimes be used instead of money, e.g.: Casino token , also known as a casino chip, check, cheque, or gaming chip
In computational complexity theory, a theorem of Valiant states that computing permanents is #P-hard, and even #P-complete for matrices in which all entries are 0 or 1 Valiant (1979). This puts the computation of the permanent in a class of problems believed to be even more difficult to compute than NP.
6-digit codes are commonly provided by proprietary hardware tokens from a number of vendors informing the default value of d. Truncation extracts 31 bits or log 10 ( 2 31 ) ≈ 9.3 {\textstyle \log _{10}(2^{31})\approx 9.3} decimal digits, meaning that d can be at most 10, with the 10th digit adding less variation, taking values of 0, 1 ...
In computer science, serializing tokens are a concept in concurrency control arising from the ongoing development of DragonFly BSD. According to Matthew Dillon , they are most akin to SPLs , except a token works across multiple CPUs while SPLs only work within a single CPU's domain.
A security token offering (STO) / tokenized IPO is a type of public offering in which tokenized digital securities, known as security tokens, are sold in security token exchanges. Tokens can be used to trade real financial assets such as equities and fixed income , and use a blockchain virtual ledger system to store and validate token transactions.
