  • Patent number: 11507659
    Abstract: Embodiments herein facilitate resisting side channel attacks through various implementations and combinations of implementations. In embodiments, this is accomplished by preventing sensitive data from consecutively following other data through potentially vulnerable resources which otherwise may cause data to leak. Where such vulnerabilities to attacks are known, suspected, or as a proactive precaution, a cleaner can be used to inhibit the sensitive data from passing through the vulnerable areas consecutively and thus inhibit the leakage. Embodiments also envision utilizing certain types of circuits to assist in preventing leakage. By using such circuits one can reduce or even potentially eliminate the requirement for cleaners as mentioned previously.

  • Patent number: 11502824
    Abstract: Generally described, one or more aspects of the present application correspond to techniques for creating encrypted block store volumes of data from unencrypted object storage snapshots of the volumes. These encryption techniques use a special pool of servers for performing the encryption. These encryption servers are not accessible to users, and they perform encryption and pass encrypted volumes to other block store servers for user access. The encryption context for the volumes can be persisted on the encryption severs for as long as needed for encryption and not shared with the user-facing servers in order to prevent user access to encryption context.

  • Patent number: 11455404
    Abstract: Aspects and features of the present disclosure can provide a trusted, privacy-preserved deduplication process by executing deduplication functions in a trusted execution environment (TEE). In some examples, encrypted, incoming user data blocks are decrypted in the TEE to produce unencrypted user data blocks. An incoming digital fingerprint or each unencrypted user data block is produced. A processing device can compare the incoming digital fingerprint to existing digital fingerprints stored in the TEE to determine a presence of the incoming digital fingerprint and hence the presence of a copy of the data block in the storage platform, and writes the encrypted. Incoming data blocks are written to storage only when necessary. The technique allows public mass storage systems to meet cybersecurity objectives while achieving the storage space efficiency that deduplication provides.

  • Patent number: 11444977
    Abstract: Web sites are crawled using multiple browser profiles to avoid malicious cloaking. Based on web page content returned from HTTP requests using the multiple browser profiles, web sites returning substantively different content to HTTP requests for different browser profiles are identified. Web sites are further filtered by common cloaking behavior, and redirect scripts are extracted from web page content that performed cloaking. Signatures comprising tokenized versions of the redirect scripts are generated and compared to a database of known cloaking signatures. URLs corresponding to signatures having approximate matches with signatures in the database are flagged for recrawling. Recrawled URLs are verified for malicious cloaking again using HTTP requests from multiple browser profiles.
