Abstract: A tenant's clear text data in a multi-tenant storage system can be encrypted using the tenant's cryptographic key to produce encrypted yet compressible data (“cryptographic data”). The cryptographic data can be encrypted using a system cryptographic key that is managed by the multi-tenant storage system and then stored. Use of the system cryptographic key allows for subsequent maintenance activities such as deduplication and compression to be performed on data stored in the multi-tenant storage system without having to access any of the tenants' cryptographic keys.

Abstract: A multi-tenant storage system can store clear text data and associated clear text checksum received from a storage tenant using their associated cryptographic key (“cryptokey”). When the clear text data is compressible, cryptographic data (“cryptodata”) is generated from a concatenation of the clear text checksum and compressed clear text data using the cryptokey. A cryptographic checksum (“cryptochecksum”) is generated from the cryptodata. When the clear text data is uncompressible, cryptographic data (“cryptodata”) is generated by encrypting the clear text data using the cryptokey with an extra verification step to make sure the clear text checksum can be rebuilt during the read request. A cryptographic checksum (“cryptochecksum”) is generated from the cryptodata. The cryptodata and associated cryptochecksum are stored in the multi-tenant storage system, so that repairs to damaged cryptodata can be made using the associated cryptochecksum.

Abstract: A blockchain network include nodes that are configured as time sources. These time-source nodes broadcast respective updates of their local times to all nodes in the blockchain network. Each node computes a summary time value based on the received local time values so that each node uses the same summary time to maintain their respective copies of the blockchain.
