  • Publication number: 20190362103
    Abstract: In described examples, a method of routing messages in a system on a chip (SoC) includes a secure message router receiving a message including a content, an identifier of the message's sending (origin) functional block and/or of a receiving (destination) functional block, a message secure value, a promote value, and a demote value. A context corresponding to the identifier is retrieved from a memory. The context includes an allow promote value and an allow demote value. The message secure value is increased if the promote value requests the increase and matches the allow promote value. The message secure value is decreased if the demote value requests the decrease and matches the allow demote value. Cleartext corresponding to the content is made accessible by the destination if the context secure value matches the message secure value. The message is then outputted from the secure message router to the destination.

  • Publication number: 20130326131
    Abstract: A security context management system within a security accelerator that can operate with high latency memories and can provide line-rate processing on several security protocols. The method employed hides the memory latencies by having the processing engines working in a pipelined fashion. It is designed to auto-fetch security context from external memory, and will allow any number of simultaneous security connections by caching only limited contexts on-chip and fetching other contexts as needed. The module does the task of fetching and associating security context with ingress packet, and populates the security context RAM with data from the external memory.

  • Publication number: 20120008768
    Abstract: An electronic data processing module (600) includes a context storage (640), cryptographic cores (615.i) adapted for acceleration of respective different types of encryption and decryption, and a mode control engine (610) responsive to a security context in said context storage (640) to operate one more selected said cryptographic cores according to a cryptographic mode at least partially specified by the security context. Other circuits and processes are also disclosed.
