M3 ideas Ideas worth sharing, from Thibaud, colleagues, partners, and customers.I made a proof of concept of the Infor ION Grid running on Crypt.DB, a database that computes on encrypted data.Fully homomorphic encryption.Lets suppose Alice is a client that is computationally bounded, she has an input X, she wants to compute an arbitrary program P on her input X and get the result where P is computationally intensive, she wants to delegate her computation to a powerful server e.The way to do this is to encrypt the input, do the computation on the cipher text, and output the encryption of the result.A fully homomorphic encryption FHE is an encryption scheme that achieves that.It is currently still impractical in its full form because the algorithms take exponential time, but it is generating a lot of research in both academia and the industry, and they are bringing variants that make it practical.Crypt. DBCrypt. DB is a practical database server that allows SQL queries on encrypted data using SQL aware encryption schemes e.The threat model for Crypt.DB is to ensure the privacy of the data in the face of a compromise of the database server.I learned about Crypt.DB during the MIT cyber security course.Microsoft Always Encrypted with SQL Server is another implementation.Proof of concept.I made a proof of concept of the Grid running on Crypt.DB. I have not followed the guidelines to optimize the encryption schemes for the Grid I just used the default Crypt.DB with the goal to spark interest in homomorphic encryption.The ideal would be to apply homomorphic encryption to M3.In this Post we will see How to Install Scala, SBT and Java on Ubuntu 16.Install Java Step 1.Preparation.

Server.Variables. if query SELECT USER then.SELECT CURRENTUSER fix for Grid Agent.Start the Grid. Start the Grid as usual see part 8.Result. The result is a Grid running transparently on Crypt.DB, unaware that the underlying data is encrypted, while Crypt.DB does the computation on the encrypted data on behalf of the Grid The Crypt.DB proxy intercepts the queries QUERY, it parses them and encrypts them NEW QUERY, it executes them on My.SQL, it decrypts the result and returns the clear text to the Grid Benefits.The advantages are that the Grid data is encrypted which preserves its privacy in case the database server is compromised, and the Grid application did not have to be rewritten for it.If someone were to compromise the database server, they would only see encrypted table names and columns and encrypted data that does not reveal information about the actual data Potential.I hope this proof of concept inspires Infor Product Development to consider this type of security for their applications that run on the multi tenant cloud, such as M3.Secure multi party computation and homomorphic encryption are the future direction for the security of multi tenant clouds and a potential market not yet realized.Install Postgresql Debian Aptget Search
