Patents by Inventor Vijayakumar P. Murty

Vijayakumar P. Murty 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: 8892881
    Abstract: The present invention is a secure access system whereby the key that facilitates entrance to electronic data is split into at least two segments. Electronic data may be accessed by the application of the key segments in combination. A server may be used to derive key segments by way of algorithms, in a manner that improves the bit security of the key. Bit strings generated by the present invention may be concatenated to form data blocks whereby plaintext may be encrypted or ciphertext decrypted. The concatenation of the unique bit string variables and the generation of bit strings of specific sizes, as may occur through padding of blocks, work to provide a secure means of encrypting a key. A different bit string may be generated for each encryption/decryption transmission which limits the opportunity for an adversary to decrypt the plaintext.
