Method and apparatus for implementing memory segment access control in a distributed memory environment

An apparatus comprising:

• at least one processor circuitry, and
• at least one memory circuitry including computer program code, the at least one memory circuitry and the computer program code configured to, with the at least one processor circuitry, cause the apparatus to at least:
• receive, from a first device via a wireless link, a request for use of shared storage capacity of the apparatus, wherein the apparatus is separate from the first device, and wherein the apparatus comprises a radio frequency memory tag;
• receive, at the apparatus and during a first write state for a memory segment at the apparatus, a cryptographic keystream in association with the request;
• store, during the first write state, the cryptographic keystream in the memory segment;
• transition from the first write state to a second write state for the memory segment;
• receive, at the apparatus and during the second write state, unencrypted data content;
• transform, at the apparatus and during the second write state, the unencrypted data content using the cryptographic keystream to form encrypted data content;
• store, during the second write state, the encrypted data content in the memory segment;
• transition from the second write state to a first read state for the memory segment;
• and
• provide, during the first read state, the encrypted data content to one or more requesting devices.

A non-transitory computer readable storage medium having program code, which when executed by at least one processor circuitry causes operations comprising:

• receiving, from a first device via a wireless link, a request for use of shared storage capacity of a second device, wherein the second device is separate from the first device, and wherein the second device comprises a radio frequency memory tag;
• receiving, at the second device and during a first write state for a memory segment at the second device, a cryptographic keystream in association with the request;
• storing, during the first write state, the cryptographic keystream in the memory segment;
• transitioning from the first write state to a second write state for the memory segment;
• receiving, at the second device and during the second write state, unencrypted data content;
• transforming, at the second device and during the second write state, the unencrypted data content using the cryptographic keystream to form encrypted data content;
• storing, during the second write state, the encrypted data content in the memory segment;
• transitioning from the second write state to a first read state for the memory segment;
• and
• providing, during the first read state, the encrypted data content to one or more requesting devices.
