Abstract
Methods, systems, and media for improving computer security and performance of security are disclosed. In one example, a computer security system comprises a key management monitor, and two key elements comprising a first key element and a second key element. The first key element is stored at a first location address within a computer memory and the second key element is stored at a second location address. The key management monitor is configured to determine or receive a time duration for performing a data dump of contents of the computer memory. In one example, the key management monitor is further configured to control a location of the first key element within the computer memory, wherein the location address of the first key element is changed within a time period that is less than the time duration for performing the data dump of contents of the computer memory.
