| 1. | New public - key system replaced the luc system
系统的一种新公钥系统 |
| 2. | A new improved public - key system of knapsack based on euler - fermats theorem
小定理实现的背包公钥密码体系 |
| 3. | The public - key system uses a pair of mathematically related sequences , one for encryption and the other for decryption
明钥系统采用一对数学上相关的序列，一个用于加密，另一个用于解密。 |
| 4. | To use a public - key system to digitally sign a message , the sender first applies a hash function to the message to create a message digest
若要使用公钥系统对消息进行数字签名，发送方先向该消息应用哈希函数以创建消息摘要。 |
| 5. | Pkp holds the patents and exclusive licensing rights to all public - key systems on behalf of rsa data security , mit , stanford university , and others
Pkp代表rsa数据安全公司、麻省理工学院、斯坦福大学和其它机构，拥有所有公开密钥系统的专利权和唯一的许可发放权。 |
| 6. | The author introduces the message digest algorithm , digital signature and x . 509 certificate which are the foundations of authentication in public - key systems . next , ssl protocol is analyzed
本文首先介绍了密码学方面的基础知识，接着介绍了身份认证中的消息摘要算法和数字签名的原理以及x |
| 7. | Because , at the bit - length of typical keys , very few numbers are primes , public - key systems must use very large keys to prevent exhaustive searches that try to guess the prime numbers used or to factor the keys
就典型钥匙的位长而言，因为素数的数目是非常少的，故公开密钥系统必须使用非常大的密钥，以防止穷尽研究把使用的素数猜出来或把密钥的因子算出来。 |
