Also, externally monitoring the timing of operations can potentially reveal sensitive data. For example, a cryptographic operation can expose its internal state if the time it takes to perform the operation varies, based on the state.\nCovert channels are frequently classified as either storage or timing channels. Some examples of covert timing channels are the system's paging rate, the time a certain transaction requires to execute, and the time it takes to gain access to a shared bus.","Incomplete","Base","Simple",false,[],{"title":85,"metaDescription":86,"keywords":87,"canonicalUrl":88,"structuredData":89},"What is CVE-2020-25657?
