The generated keys may be transferred from the key controller block of the chip to an on-chip bus interface block via a secure serial link. The transferred keys may be stored in registers which may be accessible by only the key controller block of the chip. In this regard, the generated keys may be written to one or more of the key registers only by the key controller block. Furthermore, a written key may be read from a key register only by the key controller block. During the transfer of a generated key, a data valid signal may be used to indicate valid keys in a data signal used to transfer the keys via the secure serial link."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and system for secure access and processing of an encryption/decryption key","description":"Secure access and processing of an encryption/decryption key may include generating one or more keys within a key controller block of a chip.
