H04L9/0847 - CPC Classification

Classification description:

arrangements for secret or secure communications Cryptographic mechanisms or cryptographic ; Network security protocols; Key distribution or management, e.g. generation, sharing or updating, of cryptographic keys or passwords; Key establishment, i.e. cryptographic processes or cryptographic protocols whereby a shared secret becomes available to two or more parties, for subsequent use; Key agreement, i.e. key establishment technique in which a shared key is derived by parties as a function of information contributed by, or associated with, each of these involving identity based encryption [IBE] schemes
