2. Stream cipher - Wikipedia

   en.wikipedia.org/wiki/Stream_cipher

   The operation of the keystream generator in A5/1, an LFSR-based stream cipher used to encrypt mobile phone conversations.. A stream cipher is a symmetric key cipher where plaintext digits are combined with a pseudorandom cipher digit stream ().

3. Exception handling (programming) - Wikipedia

   en.wikipedia.org/wiki/Exception_handling...

   Microsoft's 32-bit Structured Exception Handling (SEH) uses this approach with a separate exception stack. [20] Dynamic registration, being fairly straightforward to define, is amenable to proof of correctness. [21] The second scheme, and the one implemented in many production-quality C++ compilers and 64-bit Microsoft SEH, is a table-driven ...

4. Cryptographically secure pseudorandom number generator

   en.wikipedia.org/wiki/Cryptographically_secure...

   In the asymptotic setting, a family of deterministic polynomial time computable functions : {,} {,} for some polynomial p, is a pseudorandom number generator (PRNG, or PRG in some references), if it stretches the length of its input (() > for any k), and if its output is computationally indistinguishable from true randomness, i.e. for any probabilistic polynomial time algorithm A, which ...

5. DOS MZ executable - Wikipedia

   en.wikipedia.org/wiki/DOS_MZ_executable

   The environment of an EXE program run by DOS is found in its Program Segment Prefix.. EXE files normally have separate segments for the code, data, and stack. Program execution begins at address 0 of the code segment, and the stack pointer register is set to whatever value is contained in the header information (thus if the header specifies a 512 byte stack, the stack pointer is set to 200h).

6. Cyclic redundancy check - Wikipedia

   en.wikipedia.org/wiki/Cyclic_redundancy_check

   To compute an n-bit binary CRC, line the bits representing the input in a row, and position the (n + 1)-bit pattern representing the CRC's divisor (called a "polynomial") underneath the left end of the row. In this example, we shall encode 14 bits of message with a 3-bit CRC, with a polynomial x 3 + x + 1.

7. Wikipedia:Stub - Wikipedia

   en.wikipedia.org/wiki/Wikipedia:Stub

   Stub templates have two parts: a short message noting the stub's topic and encouraging editors to expand it, and a category link, which places the article in a stub category alongside other stubs on the same topic. The naming for stub templates is usually topic-stub; a list of these templates may be found here.
