Additional security in flashless modem

摘要

Various systems and methods for implementing additional security in a flashless modem are described herein. A modem system for implementing additional security in a flashless modem, the modem system comprising: local storage; non-volatile random access memory (NVRAM); and an access control module to: read non-volatile memory data (NVM data) from the local storage; calculate a hash of the NVM data; access a previously-stored hash; compare the hash of the NVM data with the previously-stored hash to produce a comparison; and control access to the NVM data based on the comparison.

1. A modem system for implementing additional security in a flashless modem, the modem system comprising:
local storage; non-volatile random access memory (NVRAM); and an access control module implemented by a hardware processor to:
read non-volatile memory data (NVM data) from the local storage;calculate a hash of the NVM data;access a previously-stored hash;compare the hash of the NVM data with the previously-stored hash to produce a comparison;control access to the NVM data based on the comparison;update the NVM data during operation of the modem system to produce updated NVM data;calculate a group-based hash of the updated NVM data; andperiodically or intermittently copy the updated NVM data and the group-based hash to the memory storage of the application processor.
