Abstract: A request associated with one or more privileges assigned to a first entity may be received. Each of the one or more privileges may correspond to an operation of an integrated circuit. Information corresponding to the first entity and stored in a memory that is associated with the integrated circuit may be identified. Furthermore, the memory may be programmed to modify the information stored in the memory that is associated with the integrated circuit in response to the request associated with the one or more privileges assigned to the first entity.

Abstract: A first instruction to store an entity identification (ID) in a memory of a device may be received. The entity ID may be stored in the memory in response to receiving the first instruction. Furthermore, a second instruction to store a value based on a key in the memory of the device may be received. A determination may be made as to whether the value based on the key that is to be stored in the memory corresponds to the entity ID that is stored in the memory. The value based on the key may be stored in the memory of the device when the value based on the key corresponds to the entity ID.

Abstract: A virtual memory including virtual addresses may be generated. A first virtual address of the virtual memory may be mapped to a first physical address of a one-time programmable (OTP) memory of a device. Furthermore, a second virtual address of the virtual memory may be mapped to a second physical address of a static memory of the device. The virtual memory that is mapped to the OTP memory and the static memory may be provided for accessing of the data of the OTP memory of the device.

Abstract: A computing device receives a feature name or key name for an integrated circuit comprising a security manager core and an additional component. At least one of a) the additional component is associated with the key name or b) a feature provided by the additional component is associated with the feature name. The computing device receives a specified number of bits associated with the feature name or the key name, and maps the feature name to a feature address space or the key name to a key interface of the security manager core based at on the specified number of bits. The computing device generates at least one hardware description logic (HDL) module based on the mapping, wherein the at least one HDL module is usable to configure the security manager core for delivery of payloads associated with the feature name or the key name to the additional component.

Abstract: A symmetric key that is stored at a device may be received. A public key from a remote entity may also be received at the device. Furthermore, a derived key may be generated based on a one way function between the symmetric key that is stored at the device and the public key that is received from the remote entity. The derived key may be encrypted with the public key and transmitted to the remote entity. The encryption of the derived key with the public key may provide secure transmission of the derived key to an authorized remote entity with a private key that may be used to decrypt the encrypted derived key.
