International Classification:

H04L 9/00

Abstract:

Techniques for mitigating timing attacks via dynamically triggered time dilation are provided. According to one set of embodiments, a computer system can track a count of application programming interface (API) calls or callbacks made by a program within each of a series of time buckets. The computer system can further determine that the count exceeds a threshold count for a predefined consecutive number of time buckets. Upon making this determination, the computer system can trigger time dilation with respect to the program, where the time dilation causes the program to observe a dilated view of time relative to real time.

International Classification:

H04L 9/00

Abstract:

Techniques for mitigating timing attacks via dynamically scaled time dilation are provided. According to one set of embodiments, a computer system can enable time dilation with respect to a program, where the time dilation causes the program to observe a dilated view of time relative to real time. Then, while the time dilation is enabled, the computer system can track a count of application programming interface (API) calls or callbacks made by a program within each of a series of time buckets and, based on counts tracked for a range of recent time buckets, scale up or scale down a degree of the time dilation.
