Method and apparatus for non-interactive information dispersal

A computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by one or more processing modules to cause the one or more processing modules to:

• dispersed storage error encode a data segment of a data object to produce a set of encoded data slices;
• obtain a secret key;
• encrypt an encoded data slice of the set of encoded data slices, utilizing the secret key, to produce an encrypted data slice;
• encrypt the secret key, utilizing a public key of a storage unit, to produce an encrypted secret key;
• combine the encrypted data slice and the encrypted secret key to create a package;
• perform a signature operation on the package to generate a signed package;
• send the signed package for receipt by the storage unit;
• receive, by the storage unit, the signed package;
• validate a signature of the signed package;
• decrypt the encrypted secret key, utilizing a private key of the storage unit, to produce the secret key;
• and
• decrypt the encrypted data slice, utilizing the secret key, to produce the encoded data slice.

A computing device comprises:

• a network interface;
• a memory storage comprising instructions;
• and
• a processing module in communication with the memory, wherein the processing module executes the instructions to:
• dispersed storage error encode a data segment of a data object to produce a set of encoded data slices;
• obtain a secret key;
• encrypt an encoded data slice of the set of encoded data slices, utilizing the secret key, to produce an encrypted data slice;
• encrypt the secret key, utilizing a public key of a storage unit, to produce an encrypted secret key for decryption and recapture by the storage unit;
• combine the encrypted data slice and the encrypted secret key to create a package;
• perform a signature operation on the package to generate a signed package for validation by the storage unit;
• and
• send, via the network interface, the signed package for receipt by the storage unit wherein the storage unit operates to determine a requester identity and an operational code associated with the signed package and validates that the requester identity is permitted to perform a request associated with the operational code.
