    • A symmetrical key code processing device and a method are provided to increase the effectiveness of speed and the power consumption by not repeating the production of the round key. A symmetrical key code processing device(200) comprises a control signal unit(201), a round key generating unit(202), a memory unit(203), a symmetric key code encoding/decoding processor(204), and input-output signal processing unit(205). The control signal unit produces the round key generating signal or the symmetric key code encoding/decoding signal. The round key generating unit produces the round key. The round key generated from the round key generating unit is stored in the memory unit. The symmetric key code encoding/decoding processor receives the round key from the memory unit, and performs the encoding/decoding process of external data.

    • A distributed RSA signature method in an ad-hoc network and a node for generating signatures are provided to process a distributed signature function without interaction between nodes by utilizing an inherent characteristic of an MDS code. In a dealer node, key information is distributed to plural nodes using RSA(Rivest Shamir Adleman) parameters and an MDS(Maximum Distance Separable) code(S301). Partial signature is generated at the plural nodes using the distributed key information and then the generated partial signature is transmitted to a signature generation node(S302). An RSA signature is generated using the partial signature at the signature generation node(S303). The RSA signature is generated using the partial signature, which is received from nodes less than the number of the plural nodes.
    • 提供了自组织网络中的分布式RSA签名方法和用于生成签名的节点,以通过利用MDS代码的固有特性来处理分布式签名功能而无需在节点之间进行交互。 在经销商节点中,使用RSA(Rivest Shamir Adleman)参数和MDS(最大距离可分离)代码(S301)将密钥信息分发到多个节点。 使用分布式密钥信息在多个节点处生成部分签名,然后将生成的部分签名发送到签名生成节点(S302)。 使用签名生成节点处的部分签名生成RSA签名(S303)。 使用部分签名生成RSA签名,所述部分签名从小于多个节点的节点的节点接收。
