OTTAWA, July 30, 2013 (GLOBE NEWSWIRE) -- Validian Corp. (OTCQB:VLDI), the first-to-market with the next generation of cyber security technology for the management and protection of digital information, data and assets, today announced a major cyber security breakthrough for protecting the storage, access and transfer of Digital Information on mobile devices.
A recent study on hardware encryption has noted that for hardware encryption, the cryptographic key is stored in a separate inaccessible portion of memory storage, thus making it more secure than software encryption. (See
The context is that all Digital Information or data is encrypted with either an asymmetrical key (as in PKI) or a symmetrical key, but in either case that Digital Information or data is always decrypted by a symmetrical key. For both hardware encryption and software encryption, that decrypting symmetrical key is always stored on the end point hardware, which in the mobile sector is the smartphone or tablet. It may be more difficult to steal that hardware encryption key than a software encryption key, but hackers know where it is located and can steal these keys to decrypt encrypted data stolen during transit.
Changing the key even once is a major undertaking requiring recoding and re-downloading or re-installing to each and every end point and therefore smartphone and tablet. Replacing symmetrical keys for the U.S. banking industry only once took 11 months and cost over $100 million (Bloomberg/June 2011).
Conversely, Validian is the first and only technology in the world that dynamically changes these symmetrical keys for each and every data transfer, so that when a symmetrical key is stolen, it is useless because it already is being replaced by a new symmetrical key that is only generated for the decryption of the particular transfer of encrypted Digital Information or data.
