Multinational computing giant is adding to its arsenal of patents with an application for improving the security of permissioned networks. The patent, first filed in October 2016, was by the Patent and Trademark Office on March 12.
The patent is entitled “Resisting replay attacks efficiently in a permissioned and privacy-preserving network,” and outlines security techniques for withstanding such attacks while maintaining valid user permissions and privacy.
In its most general sense, a is a valid data transmission that is maliciously or fraudulently repeated or delayed. IBM’s background for its patent explains this threat within the context of blockchains, outlining that:
“In a replay attack the attacker simply ‘replays’ a message that was ‘eavesdropped’ on from the network or that the attacker ‘saw’ on the . Such a replay would cause the validators to include this new transaction in the , and thus repeat the result of that transaction without the original creator of the transaction intending this.”
IBM’s invention for resisting this possibility within the context of a permissioned entails a method of communication and securing the validation of transactions within a network of computer systems:
“In a network of computer systems, a method of communication may comprise at a user computer system, generating a security value that is to be used only once, generating a message signed with a security certificate and including the security value, and transmitting the message over the network of computer systems.”
Various embodiments of IBM’s invention outline how validator permissions for each of the networked systems are to be secured. This involves generating a transaction that is “signed with a security certificate and includes a [unique] security value” (to be used only once), which indicates that a network of computer systems is eligible to execute a transaction, before it is transmitted onward.
As Cointelegraph has , a data survey of -related patents filed by August 2018 revealed that was virtually neck-and-neck with ’s in terms of the highest number of such patents filed by a global entity.
Just last week, the tech giant two new patent applications, one targeted at network security and the second focused on using to streamline database management systems.
