SECURE ENVIRONMENT FOR SUBSCRIBER DEVICE

摘要

A secure lock procedure for mobile devices is disclosed. The secure lock process generally includes detecting a device access attempt at a telecommunication device during a security-enabled boot sequence. The device access attempt may include a cryptographic key, which when detected, initiates a cryptographic authentication operation. The cryptographic authentication operation results in access to one or more resource of the telecommunication device being enabled, when the cryptographic key is determined to be valid, or denied, when the cryptographic key is determined to be invalid. The device access attempt may be associated with a root-level device access attempt or software flash attempt, and the secure lock procedure can be implemented in conjunction with a boot loader stored within a memory of the telecommunication device.
