Abstract: Methods and systems for cryptography use a reconfigurable platform to perform cryptographic functions. Where a reconfigurable platform is use the configuration may be used as a key or secret. The function schema may be maintained as public. The reconfigurable platform may be implemented in a manner to provide desirable families of functions, including reconfigurable functions which are pseudo one-way and pseudo random. An electronic device may include a reconfigurable platform adapted to perform cryptographic functions wherein a configuration of the reconfigurable platform is used as a secret.

Abstract: The present invention relates to identification, isolation, characterization and use of a novel gene OSISAP1 obtained from rice and its corresponding novel protein sequence; also relates to a method of over-expressing the novel gene OSISAP1 encoding a zinc-finger stress associated protein from rice conferring salt, cold and drought stress tolerance in transgenic plant systems, further this invention also relates to transgenic plants, plant tissues and plant seeds having a genome containing the novel gene OSISAP1 and a method of producing such plants and plant seeds.
