  • Variable-length nonce generation
    Patent number: 8572231
    Abstract: Methods and systems for obtaining a scalable variable-length nonce are provided. An exemplary method for obtaining a scalable variable-length nonce includes obtaining an initial nonce candidate. The exemplary method also includes transmitting a query to determine whether the initial nonce candidate has already been assigned. When the initial nonce candidate has already been assigned, a combined nonce candidate is obtained. The combined nonce candidate includes characters appended to the initial nonce candidate. An exemplary system for obtaining a scalable variable-length nonce includes a transmitting engine that transmits a request associated with a current token. The exemplary system also includes a receiving engine that receives a message associated with the current token. The exemplary system further includes a token acquiring engine that obtains a new token, and an appending engine that appends the new token to the current token.
