Sriram Kottarakurichi Rajamani has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10601596
    Abstract: Techniques to secure computation data in a computing environment from untrusted code. These techniques involve an isolated environment within the computing environment and an application programming interface (API) component to execute a key exchange protocol that ensures data integrity and data confidentiality for data communicated out of the isolated environment. The isolated environment includes an isolated memory region to store a code package. The key exchange protocol further involves a verification process for the code package stored in the isolated environment to determine whether the one or more exchanged encryption keys have been compromised. If the signature successfully authenticates the one or more keys, a secure communication channel is established to the isolated environment and access to the code package's functionality is enabled. Other embodiments are described and claimed.
