The next creation pertains to the specialized subject of information encryption and, much more specially, to an apparatus and method for making use of a parity procedure to encrypt information for defense.
Due to the value of intellectual house, manufacturers generally encrypt details connected for their intellectual residence (Ip), like packages, off-line to safeguard the data and retailer the encrypted data in non-volatile memory or storage medium in order that an unauthorized man or woman won't restore the information can, regardless of whether he / she receives the storage or storage medium along with the encrypted data.
U.S. patent 6,408,073 issued to Hsu et al. for an "encryption circuit to safeguard knowledge in read-only memory" discloses an encryption circuit for protecting knowledge saved in read-only memory (ROM) by implementing each a pseudo-random generator and an initial price seed 1 / seed two to encode ROM data to generate encoded details. Nevertheless, because encryption technologies makes use of random figures as parameters, such a details security approach involves a synchronous random number generator for decryption. It also takes several random number designs to properly avoid an unauthorized individual from retrieving data or courses, which suggests that a pseudo-random quantity generator requires hugely advanced circuitry for encoding and decoding. As a result, the fee improves radically. In contrast, a straightforward pseudo-random variety generator for coding and decoding may be used to avoid wasting expenses, but in this manner facts and applications is usually effortlessly accessed by an unauthorized human being.
The object in the current invention will be to give a device and a system for making use of a parity procedure to encrypt facts for cover, thus preventing the complex pseudo-random generator from the prior artwork and for that reason conserving expenditures, too because the load on the processor Keep away from condition of your artwork and as a consequence raise performance.
In accordance with a single element of the present invention, you can find presented an apparatus for applying a parity procedure to encrypt info for cover. This gadget contains: a parity generator, a first parity place generator and also a parity insertion device. The parity generator generates a parity bit in accordance using a day for being output, the date comprising a plurality of bits. The main parity point generator generates an insertion placement N (positive integer) for your parity in accordance which has a predetermined algorithm. The parity inserting unit inserts the parity little bit into a position concerning the (N-1) th and Nth bits in the date in accordance while using the insertion posture N, therefore building encrypted knowledge.
With our pioneering parity generator and checker save yourself an unnecessary hustle and choose your best fit from our extensive range of established products.
In accordance with one more element of the present creation, there is supplied a way of implementing a parity procedure to encrypt knowledge for protection. This process involves: (A) building a parity little bit in accordance having a day to generally be output, the day owning a plurality of bits; (B) producing an insert place N (constructive integer) with the parity bit in accordance by using a predetermined algorithm; (C) inserting the parity bit into a posture involving the (N-1) th and Nth bits of your date in accordance with all the insert situation N generated in action (B), thereby building encrypted data.
In accordance with however a different object of the existing creation, there exists presented an apparatus for implementing check bits to encrypt details for cover. This machine comprises: a verify bit generator that generates p check bits by a verify algorithm system in accordance using a details to generally be output, where p is an integer larger than or equal to 1; a primary check out bit place generator which generates insertion positions N 1 , ..., N p (a favourable integer each and every for N, p) for the p test bits in accordance with a predetermined algorithm; in addition to a examine little bit insertion unit which locations the p test bits in a very posture concerning the (N x -1) -th and (N x) -th bit in the info in accordance while using the insertion positions N one , ..., N p , which were being generated because of the very first test bit position generator, where x = 1, ..., p, therefore developing an encrypted datais made.
In accordance with one more element of the current invention, there is certainly delivered a way of applying verify bits to encrypt details for cover. This method incorporates: (A) producing p examine bits by a verify algorithm product in accordance with a day for being output, the place p is undoubtedly an integer better than or equivalent to 1; (B) generating insertion positions N 1 , ..., N p (every single a favourable integer for N, p) with the p check bits in accordance with a predetermined algorithm; and (C) inserting the p examine bits just about every into a position concerning the (N x -1) th and (N x ) th bits of your facts in accordance together with the insert positions N one , ..., N pgenerated in action (B), in which x = one, ..., p, whereby the encrypted info is produced.
