问题 阅读理解与欣赏

  我不敢说生命是什么,我只能说生命像什么。生命像向东流的一江春水,他从最高处发源,冰雪是他的前身。他聚集起许多细流,合成一股有力的洪涛,向下奔注,他曲折地穿过了悬岩峭壁,冲倒了层沙积土,挟卷着滚滚的沙石,快乐勇敢地流走,一路上他享受着他所遭遇的一切。有时候他遇到巉岩前阻,他愤激地奔腾了起来,怒吼着,回旋着,前波后浪地起伏催逼,直到冲倒了这危崖,他才心平气和地一泻千里。有时候他经过了细细的平沙,斜阳芳草里,看见了夹岸红艳的桃花,他快乐而又羞怯,静静地流着,低低地吟唱着,轻轻地度过这一段浪漫的行程。有时候他遇到暴风雨,这激电,这迅雷,使他心魂惊骇,疾风吹卷起他,大雨击打着他,他暂时浑浊了,扰乱了,而雨过天晴,又加给他许多新生的力量。有时候他遇到了晚霞和新月,向他照耀,向他投影,清冷中带些幽幽的温暖;这时他只想休憩,只想睡眠,而那股前进的力量,仍催逼着他向前 ……终于有一天,他远远地望见了大海,啊!他已到了行程的终结,这大海,使他屏息,使他低头,她多么辽阔,多么伟大!多么光明,又多么黑暗!大海庄严地伸出臂儿来接引他,他一声不响地流入她的怀里。他消融了,归化了,说不上快乐,也没有悲哀!也许有一天,他从海上蓬蓬的雨点中升起,飞向西来,形成一道江流,冲倒两旁的石壁,来寻夹岸的桃花。然而我不敢说来生,也不敢信来生!

PKI solutions can enable a number of security services, including p authentication and non-repudiation of transactions.
eToken enables the users of PKI systems to generate and store (101) and digital certificates inside the token, creating a secure environment and allowing full portability and maximum ease of use. eToken Pro can also perform sensitive on-chip (102) operations, ensuring that users’ keys axe never exposed to the PC environment, eToken eliminates the need to store (103) and keys on a hard disk or browser file, or to transmit them across the Internet/Extranet; assuring peace-of-mind and confidence during online communications.
A digital signature is created using the private key of an individual to ensure the Validity of his request. This technology can be used to guarantee (104) of various transactions. The strength of either the authentication level or the digital signature relies on the level of protection offered to the private key. eToken Pro offers the maximum level of security, since it enables the use of the private key for signing and authenticating inside the eToken.
The most secure use of authentication involves enclosing at least one certificate with every signed message. The message (105) verifies the certificate using the CA’s public key. If the sender’s public key is legitimate, the recipient verifies the message’s signature.
