生物技术方法可以用于密码学。这里展示了基于DNA二进制链的两种不同的加密方法。第一种方法展示了如何将DNA二进制链用于隐写术，这是一种通过信息隐藏进行加密的技术，以提供快速加密和解密。在假定拦截者与加密消息的发送者和接收者具有相同的技术能力的情况下，证明了基于DNA二进制链的DNA隐写是安全的。这里显示的第二种方法是基于隐写术和二进制凝胶图像的图形减法。II可用于构成分子校验和，并可与支持加密的第一种方法相结合。在用DNA条形码标记有机和无机材料的背景下，DNA密码学可能会变得具有实际意义。(C)2000爱思唯尔爱尔兰科学有限公司。保留所有权利。
Biotechnological methods can be used for cryptography. Here two different cryptographic approaches based on DNA binary strands ale shown. The first approach shows how DNA binary strands can be used for steganography, a technique of encryption by information hiding, to provide rapid encryption and decryption. It is shown that DNA steganography based on DNA binary strands is secure under the assumption that an interceptor has the same technological capabilities as sender and receiver of encrypted messages. The second approach shown here is based on steganography and a method of graphical subtraction of binary gel-images. II can be used to constitute a molecular checksum and can be combined with the first approach to support encryption. DNA cryptography might become of practical relevance in the context of labelling organic and inorganic materials with DNA 'barcodes'. (C) 2000 Elsevier Science Ireland Ltd. All rights reserved.
