Chandra Sekhar Suram 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).

  • Secure communication device and method
    Patent number: 9516065
    Abstract: A security enhancement to IPSec processing is achieved by changing the algorithms used at each re-key after expiration or termination of a Security Association session between two peer nodes. The solution enables an Internet Key Exchange to negotiate multiple algorithms to ensure that every renewed IPSec Security Association has a different algorithm combination, thereby making attempts at decryption by an attacker more difficult.
    Type: Grant
    Filed: December 23, 2014
    Date of Patent: December 6, 2016
    Assignee: FREESCALE SEMICONDUCTOR, INC.
    Inventors: Chandra Sekhar Suram, Amruta Deshpande, Jyothi Vemulapalli

  • STORAGE AND RETRIEVAL OF INFORMATION USING INTERNET PROTOCOL ADDRESSES
    Publication number: 20150295883
    Abstract: A method for storing information in a memory using an IP address having numerical fields, where penultimate and ultimate memory banks for the IP address are allocated from the memory. A penultimate pointer is stored in a location of the penultimate memory bank indexed by the value of a penultimate numerical field in the IP address. The penultimate pointer points to the ultimate memory bank. The information is stored in a location of the ultimate memory bank indexed by the value of an ultimate numerical field in the IP address.
