Group Membership Events Sample Clauses

Group Membership Events. A comprehensive group key agreement solution must handle adjustments to group secrets subsequent to all member- ship change operations in the underlying group communication system. We distinguish among single and multiple member operations. Single member changes include member join or leave. Leave occurs when a member wants (or is forced) to leave a group. While there might be different reasons for member leave – such as voluntary leave, involuntary disconnect or forced expulsion – we believe that group key agreement must only provide the tools to adjust the group secrets and leave the rest up to the higher-layer (application- dependent) security mechanisms. Multiple member changes can also be additive and subtractive. We refer to the former operation as group merge, in which case two or more groups merge into a single group. We refer to the latter as group partition, whereby a group is split into smaller groups. A group partition can take place for several reasons two of which are fairly common: 1. Network failure – a network event causes disconnection within the group. Consequently, a group is split into fragments some of which are singletons while others (those that maintain mutual connectivity) are sub-groups. 2. Explicit (application-driven) partition – the application decides to split the group into multiple components or exclude multiple members at once. Similarly, a group merge be either voluntary or involuntary: 1. Network fault heal – a network event causes previously disconnected network partitions to reconnect. Conse- quently, groups on all sides (and there might be more than two sides) of an erstwhile partition are merged into a single group. 2. Explicit (application-driven) merge – the application decides to merge multiple pre-existing groups into a single group. (The case of simultaneous multiple-member addition is not covered.) At the first glance, events such as network partitions and fault heals might appear infrequent and dealing with them might seem a purely academic exercise. In practice, however, such events are common due to network misconfigura- tions and router failures. In [25], Xxxxx et al. offer some compelling arguments in support of these claims. We consider coping with group partitions and merges to be a crucial component of group key agreement. In addition to the aforementioned membership operations, periodic refreshes of group secrets are advisable so as to limit the amount of ciphertext generated with the same key and to r...
