RSA 非對稱加密

RSA簡介

RSA加密算法是一種非對稱加密算法。在公開密鑰加密和電子商業(yè)中RSA被廣泛使用。RSA是1977年由羅納德·李維斯特（Ron Rivest）、阿迪·薩莫爾（Adi Shamir）和倫納德·阿德曼（Leonard Adleman）一起提出的。當(dāng)時他們?nèi)硕荚?span id="tf11vwa" class="wpcom_tag_link">麻省理工學(xué)院工作。RSA就是他們?nèi)诵帐祥_頭字母拼在一起組成的。

假如有人找到一種快速因數(shù)分解的算法的話，那么用RSA加密的信息的可靠性就肯定會極度下降。但找到這樣的算法的可能性是非常小的。今天只有短的RSA鑰匙才可能被強力方式解破。到目前為止，世界上還沒有任何可靠的攻擊RSA算法的方式。只要其鑰匙的長度足夠長，用RSA加密的信息實際上是不能被解破的。

1983年麻省理工學(xué)院在美國為RSA算法申請了專利。這個專利2000年9月21日失效。由于該算法在申請專利前就已經(jīng)被發(fā)表了，在世界上大多數(shù)其它地區(qū)這個專利權(quán)不被承認。

RSA應(yīng)用過程

非對稱算法的在應(yīng)用的過程如下:

• 接收方生成公鑰和私鑰，公鑰公開，私鑰保留；
• 發(fā)送方將要發(fā)送的消息采用公鑰加密，得到密文，然后將密文發(fā)送給接收方；
• 接收方收到密文后，用自己的私鑰進行解密，獲得明文。

設(shè)置URL有效時長

為了增強URL安全性，前端在header中添加時間戳。

前端代碼

在header中添加時間戳

2.2 后端驗證時間戳

private Long getDateTimestamp(HttpHeaders httpHeaders) { List list = httpHeaders.get(“timestamp”); if (CollectionUtils.isEmpty(list)) { throw new IllegalArgumentException(“拒絕服務(wù)”); } long timestamp = Long.parseLong(list.get(0)); long currentTimeMillis = System.currentTimeMillis(); //有效時長為5分鐘 if (currentTimeMillis – timestamp > 1000 * 60 * 5) { throw new IllegalArgumentException(“拒絕服務(wù)”); } return timestamp; }

測試不傳時間戳

確保URL唯一性

確保URL唯一性，前端請求中增加UUID，后端存入redis，有效時長為5分鐘，5分鐘重復(fù)提交拒絕服務(wù)

修改前端請求參數(shù)

3.2 后端增加驗證RequestId

private String getRequestId(HttpHeaders headers) { List list = headers.get(“requestId”); if (CollectionUtils.isEmpty(list)) { throw new IllegalArgumentException(ERROR_MESSAGE); } String requestId = list.get(0); //如果requestId存在redis中直接返回 String temp = redisTemplate.opsForValue().get(requestId); if (StringUtils.isNotBlank(temp)) { throw new IllegalArgumentException(ERROR_MESSAGE); } redisTemplate.opsForValue().set(requestId, requestId, 5, TimeUnit.MINUTES); return requestId; }
