Security testing of a secure cache design

Content Provider ACM Digital Library
Author Liu, Fangfei Lee, Ruby B.
Abstract Cache side channel attacks are attacks that leak secret information through physical implementation of cryptographic operations, nullifying cryptographic protection. Recently, these attacks have received great interest. Previous research found that software countermeasures alone are not enough to defend against cache side channel attacks. Secure cache designs can thwart the root causes of cache side channels and are more efficient. For instance, Newcache is a cache design that can enhance security, performance and power efficiency simultaneously through dynamic memory-cache remapping and eviction randomization. However, these cache designs seldom had their security verified experimentally by mounting cache side channel attacks on them. In this paper, we test the security of Newcache using representative classes of cache side channel attacks proposed for conventional set-associative caches. The results show that Newcache can defeat all these attacks. However, what if a very knowledgeable attacker crafted the attack strategy targeting the secure caches design? We redesign the attacks specifically for Newcache. The results show that Newcache can defeat even crafted access-driven attacks specifically targeted at it but sometimes succumbs to the specifically crafted timing attacks, which is due to a very subtle vulnerability in its replacement algorithm. We further secure Newcache by modifying its replacement algorithm slightly, thus defeating these specifically crafted timing attacks. In addition, the improved Newcache simplifies the replacement algorithm in the original Newcache design.

About National Digital Library of India (NDLI)
NDLI logo

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
