WebThe deterministic encryption algorithm ensures that a given input value always encrypts to the same output value each time the algorithm is executed. While deterministic encryption provides greater support for read operations, encrypted data with low cardinality is susceptible to frequency analysis recovery. WebThe deterministic encryption algorithm ensures a given input value always encrypts to the same output value each time the algorithm is executed. While deterministic encryption provides greater support for read operations, encrypted data with low cardinality is susceptible to frequency analysis recovery. greater cambridge planning policyWebAs with encryption in general, this involves a public key and a private key. When an initiator node v 0 wants to send a message to a receiver node v, it will use v’s public key to encrypt the message; then only v can decrypt it, using its private key. greater cambridge planning advice
