  Abstract: The widely deployed Least-Recently Used (LRU) cache replacement policy and its variants are an essential component of modern processors. However, we show for the first time in detail that the LRU states of caches can be used to leak information. The LRU states are shared among all the software that accesses the cache and we show that timing-based channels are possible: any access to a cache by a sender will modify the LRU states, and the receiver is able to observe this through a timing measurement. This paper presents LRU timing-based channels both when the sender and the receiver have shared memory, e.g., shared library data pages, and when they are fully separate processes without shared memory. In addition, the new LRU timing-based channels are demonstrated on both Intel and AMD processors in scenarios where the sender and the receiver are sharing the cache in both hyper-threaded setting and time-sliced setting. The transmission rate of the new LRU channel can be up to 600Kbits/s per cache set in the hyper-threaded setting. Different from the existing cache channels which require the sender to have cache misses, the new LRU channels work with cache hits, making the channel faster and more stealthy as no cache misses are required for the sender. This paper also demonstrates that the new LRU channels can be used in transient execution attacks, e.g., Spectre, to retrieve the victim's secret. Further, this paper presents evaluation showing that the LRU channels also pose threats to existing secure cache designs. Possible defenses against the LRU timing-based channels are discussed and evaluated in simulation, with defense features added to protect the LRU states.
