新模式CCM(Counter with CBC-MAC)可以理解为4中CMAC的进阶版,额外提供了保密性。生成的MAC tag的推荐长度要大于8字节(a value of Tlen that is less than 64 shall not be used without a careful analysis of the risks of accepting inauthentic data as authentic) 新模式GCM(Galois counter mode)除了实现加...
Implementation of the new LAN security standard 802.1ae (MACSec) requires the NIST standard AES cipher in the GCM mode for encryption and message authentication (AES-GCM). The GCM1 AES core is tuned for 802.1ae applications at the data rates of 1 Gbps and higher. The GCM2 family of ...
and authenticity for the encrypted data and authenticity for the additional authenticated data (AAD). The AAD is not encrypted. GCM mode requires that the IV is a nonce, i.e., the IV must be unique for each execution of the mode under the given key. The steps for GCM encryption are: ...
GPU-Assisted AES Encryption Using GCM 来自 Springer 喜欢 0 阅读量: 59 作者: G Schönberger,J Fuß 摘要: In this paper we present an implementation of the Galois/Counter Mode (GCM) for the Advanced Encryption Standard (AES) in IPsec allowing Gigabit throughput. GCM is a so called "...
GCM : 伽罗瓦/计数器模式(Galois/Counter Mode) 其中CBC、CTR、GCM是较为常用的分组模式,他们都需要一个随机初始化向量IV。 分组模式是对块加密的协同组织算法,而块加密的具体算法则是每个对称加密算法的核心。不同的对称加密算法其块加密的算法逻辑自然各不相同,我们将在学习完分组模式后,在后续章节单独学习两个具...
This memo describes the use of the Advanced Encryption Standard (AES) in Galois/Counter Mode (GCM) as a Transport Layer Security (TLS) authenticated encryption operation. GCM provides both confidentiality and data origin authentication, can be efficiently implemented in hardware for speeds of 10 giga...
AES-GCM是高级加密标准(AES)的一种工作模式,全称是Galois/Counter Mode。 它是一种有效的authenticated encryption算法,无需额外的认证算法,AES-GCM自带认证功能,可以同时完成加密和认证。 AES-GCM模式的主要特点有: 基于AES算法,使用AES的密码块进行加密操作 ...
The AES-GCM-X can process 128 bits/cycle and the AES-GCM-X2 can process 256 bits/cycle respectively independent of the key size. GCM stands for Galois Counter. GCM is a generic authenticate-and-encrypt block cipher mode. A Galois Field (GF) multiplier/accumulator is utilized to generate...
