Abstract: A method for secure key agreement among a subset of a plurality of transceivers includes generating a first ordered subset of a plurality of keys kλj, where j=0 to S. Each of the subset of the plurality of transceivers may possess at least one of the plurality of keys kλj from the first ordered subset. Each of the subset of the plurality of transceivers possessing one or more keys kλi, i=1 to S, also possesses at least one key from a second ordered subset of the plurality of keys kλj, j=0 to i−1. A key with index λ0 is designated as a group key. A binary sum of the group key kλ0 and a key kλj, where j≠0, is transmitted from one or more of the subset of the plurality of transceivers that possesses the group key kλ0.

Abstract translation: 一种用于多个收发器的子集之间的安全密钥协商的方法包括：生成多个密钥kλj的第一有序子集，其中j = 0至S。多个收发器中的每个子集可以具有 来自第一有序子集的多个密钥kλj。 拥有一个或多个密钥kλi，i = 1至S的多个收发器的每个子集还具有来自多个密钥kλj，j = 0至i-1的第二有序子集的至少一个密钥。 索引λ0的键被指定为组密钥。 组密钥kλ0的二进制和和其中j≠0的密钥kλj从具有组密钥kλ0的多个收发器的一个或多个子集发送。
