DRAM

A random number appended to a password before hashing to increase randomness and ensure uniqueness in the resulting stored hash value. This is also known as a cryptographic salt. Salt is a string of random (or pseudorandom) bits concatenated with a key or password to reduce the probability of precomputation attacks.

A method of watermarking that hides data within the continuous random texture patterns of an image. The technique is implemented by copying a region from a random texture pattern found in a picture to an area that has similar texture, resulting in a pair of identically textured regions in the picture.

A type of computer memory that can be accessed randomly; that is, any byte of memory can be accessed without touching the preceding bytes. RAM is the most common type of memory found in computers and other devices, such as printers. There are two basic types of RAM: dynamic RAM (DRAM) and static RAM (SRAM).

The area in a computer that serves as temporary storage for programs and data during program execution. The main memory resources directly available to a system’s CPU. Primary memory normally consists of volatile random access memory (RAM) and is a high- performance storage resource available to a system.

A hidden software or hardware mechanism that permits system protection mechanisms to be circumvented. It is activated in some nonapparent manner; for example, a special “random” key sequence at a terminal. Synonymous with back door. Undocumented command sequence that allows software developers to bypass normal access restrictions.
