Abstract:
In some embodiments, a first device may generate a data block for an ordered set of data blocks such that the data block is cryptographically chained to a given data block preceding the data block in the ordered set. The first device may obtain an encryption key used to encrypt information related to the data block, and use group members' keys to encrypt the encryption key to generate a group key. As an example, the group's members may include a first member associated with the first device and other members. The keys used to encrypt the encryption key may include the other members' keys. The first device may transmit the ordered set and the group key to a communication resource (e.g., accessible by the members). Other devices (associated with the other members) may use the ordered set and the group key to obtain content related to the ordered set.

Claim (Index 1):
A system for decrypting a file, the system comprising:\n one or more processors; and memory, including instructions executable by the one or more processors to cause the system to at least: receive a plurality of file segments and encrypted file description data; decrypt the identity of each of the file segments in the plurality of file segments and of an encryption key that is associated with each file segment in the plurality of file segments; download a plurality of encrypted file segments generated from the plurality of file segments; decrypt each encrypted file segment of the plurality of encrypted file segments using the encryption key that is associated with each file segment in the plurality of file segments; and combine each decrypted file segment into a copy of a file.
